A lid locking device of the present invention is provided with a power transmission mechanism which includes a worm gear, a worm wheel, a pressurizing protrusion portion, a pressurized face and an interference avoiding space between a motor and a locking member. The power transmitting mechanism transmits backward-driving power which allows the locking member to move backward to an unlocked position from the motor to the locking member but does not transmit the power from the locking member to the motor and cuts off the power. That is, the backward driving power received by the locking member from an engagement protrusion piece of a lid on closing the lid is cut off by the power transmitting mechanism and not transmitted to the motor.

Lid locking device

A lid lock device attached to a vehicle includes: a housing; and a lock member which includes a main shaft portion, an intermediate portion extending from the main shaft portion, and a tip end portion extending from the intermediate portion and thinner than the main shaft portion, which is provided in the housing to be movable in an axial direction, and in which at least the tip end portion and the intermediate portion are disposed outside the housing, wherein the intermediate portion is configured to be narrow from the main shaft portion side toward the tip end portion side and the intermediate portion is provided with at least one inclination surface inclining downward in a direction toward the outside of the vehicle in a width direction of the vehicle and inclining to a central axis in a direction toward the tip end portion.

Lid lock device

In a lid locking device of the present invention, a first rod constituting portion at the front end of a rod is eccentrically located on a side of the rod which is a side spaced away from the lid at a forward extending region of the second rod constituting portion linearly movably supported at the tip cylindrical portion. Therefore, even where an engagement protrusion piece presses a side close to the lid of a tip swelling face of the first rod constituting portion, the device of the present invention is able to receive an axial force F derived from pressing force at a position closer to the central axis of the second rod constituting portion and also decrease in resistance on operation of closing the lid compared to a conventionally structured device.

Lid locking device and lid locking mechanism

A lid lock device includes: a housing configured to be fixed to a vehicle; a lock member configured to be movably assembled in the housing and to lock a lid of the vehicle in a closed state; a driving source configured to be assembled in the housing and to drive the lock member toward a side where the lock is released; a side surface through-hole formed at a position that opposes a side surface of the lock member in the housing; and a protrusion which is formed in a side surface of the lock member, passes through the side surface through-hole to protrude from the housing, and receives a manual operation force for moving the lock member toward the side where the lock is released.

A lid lock device includes: a housing including a first housing and a second housing assembled to the first housing and fixed to a vehicle; a lock member movably supported by one or both of the first and second housings and moving between a lock position and a lock releasing position; a surrounding sidewall protruding toward the second housing from the first housing and surrounding a surface of the first housing; a support hole provided in a front side portion of the first housing; a passage port provided in a portion of the surrounding sidewall; a blocking portion protruding toward the first housing from the second housing and blocking the passage port; and an overlapping portion formed in an opening edge of the passage port and overlapping an outer surface of an edge portion of the blocking portion.

A lid lock device includes: a housing fixed to a vehicle; a lock member assembled to the housing and movable between a lock position and a lock releasing position; a motor assembled to the housing and driving the lock member; a worm gear and a worm wheel assembled to the housing and engaged with each other to transmit power of the motor to the lock member; a wheel sidewall provided in the worm wheel, formed by bending a band plate in an arc or circular shape, having a gear portion engaged with the worm gear on the wheel sidewall, and having a gear rear side surface facing a center side of the worm wheel on the wheel sidewall; and a deformation restriction protrusion provided in the housing, the deformation restriction protrusion restricting movement toward the inside of the wheel sidewall.

A lid lock apparatus for a vehicle includes a housing, a moving member supported within the housing, and a biasing member to bias the moving member in a direction in which the moving member engages with the lid member, the biasing member including a coil portion wound in a spiral shape and arranged at a lower side of the moving member so that an axial center of the coil portion is in a skewed position relative to an axis of the moving member, a fixed arm extending from a first end portion of the coil portion to engage with the housing, and a moving arm extending from a second end portion of the coil portion to engage with the moving member, the moving arm being deflected in a circumferential direction of the coil portion relative to the fixed arm by a movement of the moving member.

Lid lock apparatus for vehicle

A lid lock apparatus for a vehicle includes a driving motor, a moving member causing a lid member provided at a vehicle body to be inhibited from opening in a state where the moving member projects from the housing to engage with the lid member, the moving member being retracted into the housing by the driving motor to release the engagement between the moving member and the lid member, and a pulling member connected to the moving member and pulled in a case where the moving member is inhibited from moving by the driving motor to cause the moving member to be retracted into the housing and to release the engagement between the moving member and the lid member. The moving member is movable relative to the pulling member in a moving direction of the moving member in a case where the pulling member is inhibited from operating.

A lid lock apparatus includes a housing formed by assembling a first body member and a second body member, a driving motor housed in the housing, an output gear, a movable member, a stopper member retained at one of the first body member and the output gear, a stopper wall formed at the other one of the first body member and the output gear and restricting the pivotal movement of the output gear by contacting the stopper member, and a stopper disengagement preventing portion formed on the other one of the first body member and the output gear, on which the stopper wall is formed, the stopper disengagement preventing portion restricting a disengagement of the stopper member in an axial direction of a rotational axis of the output gear by contacting the stopper member in the axial direction of the rotational axis of the output gear.

Lid lock apparatus

A lid lock apparatus for a vehicle includes a retainer, a cap, and a lock pin. The retainer includes a fitting portion to which an end portion of the cap is configured to fit from an outside of the lid box towards an inside of the lid box and a first engaging portion formed to be positioned outward of the lid box relative to the fitting portion. The cap includes an operational lever portion configured to be elastically deformed to tilt by an operation at an outside of the lid box and including a second engaging portion configured to engage with and disengage from the first engaging portion.

A door lock device for a vehicle includes an operating mechanism being selectable of a locked state where a latched state, between a latching member and a latched member, being unreleasable and an unlocked state where the latched state being releasable, an active lever being rotatable between a locked position and an unlocked position thereof, and an open link disabling a transmission of an operational force of a handle to the latched member under the locked state and allowing a transmission of the operational force of the handle to the latched member under the unlocked state. The active lever, provided with an elongated bore, is supported by a housing which houses the operating mechanism to be rotatable. The open link is operatively connected to the handle to be slidably supported by the housing and is provided with an engaging portion which engages with the elongated bore to be slidable therein.
