A door opening and closing apparatus for a vehicle includes a latch unit holding a vehicle door in a closed state, a lift lever operatively connected to the latch unit, an open lever operatively connected to the lift lever, a locking lever switching a locking knob between a locked stated and an unlocked state, the locking lever including a first lever connected to the open lever and a second lever connected to the first lever for relative rotation with a predetermined angle, the second lever operated by a locking actuator, a biasing member disposed between the first lever and the second lever to bias the second lever in a direction of an original position, and an outside lever including an outside handle lever connected to the outside handle and a release lever connected to the lift lever and operated by a release actuator.

Door opening and closing apparatus for vehicle

A door handle device for vehicle rotatably supported by a vehicle door includes a handle portion extended in a first radial direction relative to a rotational axis and positioned outside the vehicle door, a lever portion extended in a second radial direction relative to the rotational axis and positioned in the vehicle door, the lever portion being connected to a connection member for transmitting operational force of door lock release to a door lock mechanism, and a counterweight provided at the handle portion.

Door handle device for vehicle

A vehicle door handle device includes a frame equipped on a vehicle door panel and a handgrip mounted on the frame and rotatable about a rotation center portion at one end portion of the handgrip. A second end portion of the handgrip forms an operation portion linked with a door lock mechanism. The handgrip is adapted to be rotated within a predetermined angle around the rotation center portion to operate the door lock mechanism when the operation portion is pulled away from the frame. A restriction mechanism is also provided to restrict chattering and/or dislocation of the handgrip from the frame. The restriction mechanism includes a projection and a groove provided between the frame and the handgrip. The projection is slidable in the groove during rotation of the handgrip and is able to contact a boundary of the groove in the inserting direction of the handgrip.

Vehicle door handle device

To provide module formation of a lever unit and an inside handle unit, a vehicular door opening and closing apparatus includes a base unit ( ) fixed to a door inner panel of a vehicular door, a compartment inner side opening operating member ( ) pivotably supported by the base unit ( ) and an open lever ( ) connected and engaged with a latch unit ( ) holding the compartment inner side opening operating member ( ) pivotably supported by the base unit ( ) and the vehicular door in a closed state relative to a vehicle body and a lever unit ( ) is supported at an inside handle unit ( ).

Vehicular door opening and closing apparatus

An outside door handle assembly includes a door handle for opening and closing a vehicle door, a case for being fixed to a door panel which stores and retains the door handle and an elastic member generating an elastic force between the door handle and the case, wherein the door handle includes a pair of arm portions which are disposed on right and left sides of the door handle respectively, the case includes two pairs of stay portions each of which are disposed on right and left sides of the case and a storing portion storing the elastic member, each of the arm portions includes a pair of groove portions which are disposed on respective surfaces of the arm portion and an opening which is connected to one of the groove portions in the depth direction of the groove portion such that a depth of the opening is larger than that of the groove portion and such that a diameter of the opening is smaller than that of the groove portion, one stay portion of each pair of stay portions includes a first axle portion which is fit into one of the groove portions of the arm portion and a second axle portion which is disposed on a tip of the first axle portion and which is fit into the opening, the other stay portion of each pair of stay portions includes a third axle portion which is fit into the other one of the groove portions of the arm portion and which is coaxial with the first axle portion and the second axle portion.

Outside door handle assembly

An outside door handle assembly for an automobile includes a handle lever that follows the motion of an outside handle. When a transverse load in excess of a predetermined value acts upon the vehicle as the result of an impact at the side thereof, the handle lever is caused to swing in the transverse direction outwardly of the vehicle against the biasing force of a spring. As a result, an opening lever in a door lock device is placed in an inoperative state so that the door will not open accidentally during a side collision.

Outside door handle assembly for automotive vehicles

An outside door handle assembly for a vehicle comprises a case mounted to a vehicle door, a handle rotatably supported by the case and having a grip portion and a pair of supporting arms extending from the grip portion, a balance weight, disposed between the pair of supporting arms in such a manner as to oppose the grip portion with respect to a rotational center of the handle, fixed to the pair of supporting arms at both ends thereof and having substantially the same weight as that of the grip portion, a shaft portion formed on one end of the balance weight and extending through one of the pair of supporting arm and an operation portion mounted to the shaft portion and connected to a door lock mechanism.

Outside door handle assembly for a vehicle

An inside door handle assembly includes a handle rotatably held on a base to be secured to a vehicle's door and a knob rotatably held on the base. The base has first, second and third upright walls. The handle is disposed with respect to the first and second upright walls to cover the top of the second upright wall and the knob is disposed with respect to the second and third upright walls. The lateral movement of the handle is limited by the knob, thereby preventing the handle from becoming detached from the base.

Inside door handle assembly for vehicles

A lid lock apparatus is comprised of a lid pivotally mounted to a vehicle-body for opening/closing an opening formed therein and movable between an opening position and a closing position, a locking mechanism which is in engagement with the lid in order to hold the lid at its closing position, a first driving mechanism associated with the locking mechanism for releasing the lid from the locking mechanism, a second driving mechanism associated with the locking mechanism for releasing the lid from the locking mechanism, and a device for assuring operations of the first driving mechanism and the second driving mechanism which are independent of the second driving mechanism and the first driving mechanism, respectively.

Lid lock apparatus

A lid lock apparatus is comprised of an opening formed in a vehicle-body, a lid pivotally mounted to the vehicle-body, a locking mechanism is connected to the plate and has a shaft which engages and disengages the lid when operated to its closed and opened condition, respectively. A driving mechanism which is arranged for releasing the engagement between the shaft and the lid when in the closed condition, is mounted on the locking mechanism and positioned in such a manner that the driving mechanism is set to be in close relationship to the plate while being perpendicular to the axis of the shaft.
