A vehicle door latch device, comprising: a housing provided in a vehicle door; a latch rotatably supported by the housing, wherein a striker provided in the vehicle body can be fitted to the latch; a pawl having a shaft portion rotatably supported by the housing, wherein the pawl is engageable with the latch to restrict rotation of the latch; a helical torsion spring having a helical portion through which the shaft portion is passed, first and second engaging legs extending radially outward in relation to the helical portion, wherein the first engaging leg is engaged with the pawl, and the second engaging leg is engaged with the housing, the helical torsion spring always urging the pawl to rotate to an engagement position where the pawl can be engaged with the latch; and a projecting wall formed in the housing, the projecting wall contacting an outer circumferential surface of the helical portion.

Vehicle door latch device

A door handle for a door of an automotive vehicle having a first gasket attached at a distal end of the door handle and a second gasket attached at a proximate end of the door handle. The first gasket and second gasket have an inner surface facing the outer surface of the door and an outer surface facing the respective ends of the door handle. The first gasket and the second gasket also include a lip formed of a resilient material, which protrudes outwardly relative to the outer surface of gaskets and extends longitudinally along the edge of the gaskets to sealingly engage the ends of the door handle. The lip is embossed so that it is recessed relative to the inner surface of the gasket to accommodate compression of the lip as the handle is displaced towards the door. A flattened portion extends from an end of the lip on the first gasket to dampen noise due to impact between the distal end of the door handle and an outer surface of the door.

An electric motorand a worm gearwere housed in a case, an output shaftof the electric motorand a fitting holeC of the worm gearwere fitted so as to be capable of freely transmitting torque and of freely moving relatively in a direction of an axis X, and a tip of the output shaftand an inner end of the fitting holeC set a gap D of separation in the direction of the axis X. Furthermore, a support sectionmaking contact with an end section of a shaft sectionA of the worm gearat the side of the electric motorthereof was provided inside the case, and a thrust force resulting from dynamic inertia of the wheel gearupon stopping of the electric motorand acting on the worm gearwas borne by the support section

Automobile door-lock drive device

A door lock device includes a latch mechanism, a lift lever, an open lever, a lock lever, an open member including a link member having an operation input portion connected to the open lever and an acting portion engageable with the lift lever, and an elastic member connecting the link member and the lock lever. When the open member is in the unlocked position, the open member engages with the lift lever by an operation of the open lever in one direction thereby allowing an operation of the lift lever. When the open member is in the locked position, the open member idly engages with the lift lever by the operation of the open lever and then becomes engaged with the lift lever in the other direction thereby prohibiting the operation of the lift lever when the open member is switched to the unlocked position from the locked position.

Door lock device

A door lock device includes a latch mechanism, a lift lever, an open lever, a lock lever including a main lever and a sub lever mounted on the main lever so as to relatively rotate thereto, a biasing member disposed between the main lever and the sub lever, and an open member. When the open member is in the unlocked position, the open member engages with the lift lever by an operation of the open lever in one direction thereby allowing the lift lever operable. When the open member is in the locked position, the open member idly engages with the lift lever by the operation of the open lever and then becomes engaged with the lift lever in the other direction thereby prohibiting the lift lever operable when the open member is switched to the unlocked position from the locked position.

A door lock system for a vehicle includes a latch mechanism, a link mechanism and a housing. The latch mechanism is adapted to a vehicle door and latches the vehicle door to a vehicle body. The link mechanism includes an electric driving source and a plurality of lever members for selectively locking and unlocking the latch mechanism. The housing accommodates the latch mechanism and the link mechanism.

Door lock system for vehicle

A door lock system for a vehicle includes a) a latch mechanism which is adapted to a vehicle door and which holds the vehicle door to a vehicle body, b) an open link which is engagable and disengagable with the latch mechanism, c) a swing lever which is connected to the open link, d) an electric driving source having a gear member, and e) a rotary gear member which is arranged between the swing lever and the electric driving source so as to be meshed with the gear member of the electric driving source. The rotary gear member is directly and engagably connected to the swing lever.

A vehicle door lock apparatus includes a lever mechanism directly connected with a key cylinder provided at the outside door handle for locking and unlocking the vehicle door in response to rotation operation of the key cylinder. The lever mechanism is provided with a key rotor directly connected with the key cylinder, and a key lever directly connected with the key rotor. An input shaft of the lever mechanism formed by the key rotor is inclinable relative to an output shaft of the lever mechanism formed by the key lever, and this inclination is absorbed through the connection between the key rotor and the key lever.

Vehicle door lock apparatus

A vehicle door lock apparatus includes a first body and a second body integrated so as to be adapted to be integrally assembled to the door. The vehicle door lock apparatus further includes guide projections formed at one of the first and second bodies, and guide grooves formed at the other of the first and second bodies. In addition, a stopper is provided for preventing the separation of integrated first and second bodies by the engagement between the guide projections and the guide grooves.

A door lock system for a vehicle includes a latch mechanism, an open link, an inside lever and a cancel lever. The latch mechanism is adapted to a vehicle door and latches the vehicle door to a vehicle body. The open link is engagable and disengagable with the latch mechanism. The inside lever is adapted to an inside handle of the vehicle door and is engagable with the open link. The cancel lever is connected to the open link and is arranged between the inside lever and the open link so as to be engagable with the inside lever when the open link is disengaged from the latch mechanism.

A door lock device includes a base plate,having horizontal wall,connected to a door lock body,and vertical wall,perpendicular to the horizontal wall,, a rotation lever,rotatably supported to the vertical wall,, a key lever,rotatably supported to a housing,of an actuator,which is secured to the vertical wall,, and a connecting lever,having one end and the other end, one end being coupled to the rotation lever,after rotation of one end to the rotation lever,, the other being coupled to the key lever,after rotation of the other end to the key lever,, the connecting lever,being in parallel and close to the connecting vertical wall,of the base plate
