A vehicle door lock device includes: a latch mechanism configured to enable a vehicle door to maintain a closed state in a vehicle body; and a lock mechanism configured to set an unlocked state or a locked state, wherein the lock mechanism includes an inside opening lever connected to an inside door handle, and capable of being operated so as to be rotatable around a lever support portion between an initial position and a maximum operation position, an opening link capable of switching between a first position and a second position, a lock operation lever capable of being operated so as to be rotatable around the lever support portion between an unlocking position and a locking position, and a lever actuating mechanism actuating the inside opening lever toward the initial position.

Vehicle door lock device

A vehicle door lock device includes an opening mechanism, a lock mechanism, and an electric actuator. The electric actuator includes an electric motor driven in accordance with a lock operation and an unlock operation, a worm provided integrally with an output shaft of the electric motor, the worm being rotated and driven by the electric motor, and a locking lever having a sector gear meshed with the worm, the locking lever being linked with an active lever. The locking lever is provided with an operation portion linked with a lock knob L provided on the indoor side of a door.

A vehicle door locking device Ao is integrated by assembling a base unit Aprovided with a latch mechanism Ato a housing unit Aprovided with an actuating mechanism for actuating the latch mechanism A. A metal sub-base plateof the base unit Ahas an attachment holefitted to a support shaftprovided in the housing unit Ain the axial direction thereof, the support shaft extending in the vehicle length direction. The attachment holeof the metal sub-base plateis fitted to the support shaft, so that the base unit Ais integrated with the housing unit A. The metal sub-base plateis provided with a receiving portionfor restraining a lean in the vehicle width direction (W direction) of a child-proof leverat a back part of the child-proof lever

Vehicle door locking device

A door lock device for a vehicle, provided with an opening lever driven as a door handle is operated, an opening link interposed between the opening lever and a lift lever of a latch mechanism, a lock operation unit for switching the opening link to an unlock position or a lock position, and a locking lever for driving the lock operation unit. A retaining portion is provided to the opening lever. The retaining portion holds the opening link at a retaining position between the lock position and the unlock position when the opening link becomes switched by the locking lever through the lock operation unit from the lock position to the unlock position with the opening link driven by the opening lever.

Door lock device for vehicle

A door lock device includes a lever mechanism which carries out lock/unlock operation in response to turn operation of a key cylinder. The lever mechanism includes a key rotor which includes a coupling hole to which an inner end of a rod is coupled in a torque transmittable manner and is rotatably assembled to a housing, and a key lever which includes a hub which is coupled to the key rotor in a torque transmittable manner and is arranged in the housing. The key lever includes a first arm which extends to radial outward direction from the hub and is capable of engaging with a first engagement portion of the active lever, and a second arm which extends to radial outward direction from the hub and is capable of engaging with a second engagement portion of the active lever.

A door lock device includes an electrical drive source, which pivots a drive member from a predetermined neutral position, and a return urging member, which returns the drive member to the predetermined neutral position. The drive member pushes a locking lever with a first engagement portion and moves the locking lever to a lock position when the drive member moves from the predetermined neutral portion in a first direction in a state in which the locking lever is arranged at an unlock position. The drive member allows the double lock lever to move to the second position and disengages the first engagement portion from the locking lever when subsequently returned to the predetermined neutral position. The drive member pushes the double lock lever with a second engagement portion when moved again from the predetermined neutral position in the first direction.
