VEHICLE DOOR-LOCKING DEVICE

摘要

In order to reduce the number of exclusive components, a vehicle door-locking device 1 is configured to be provided with a locking/unlocking unit 7 that includes a locking/unlocking mechanism for switching whether or not a door-opening operation on a door is transmitted to a latch mechanism, and a transmission means 3 for transmitting a locking/unlocking operation performed with a key to the locking/unlocking unit. The locking/unlocking unit has: a main case 2 for accommodating the locking/unlocking mechanism and supporting the latch mechanism; an input member 6 that has a rotating shaft 6a passing through the main case, the input member being linked with the locking/unlocking mechanism inside the main case, and having an external linking part 6b outside the main case; and a cover for covering the opening of the main case. The transmission means has a first linking member 35 for linking the external linking part and a rotation-receiving member 34 that rotates integrally with a rotor of a key cylinder. The external linking part protrudes from the main case toward the vehicle exterior once the main case has been attached to the door.
