Abstract

A vehicle door lock device includes a latch mechanism holding and releasing a striker of a door; a locking/unlocking member switching between locking and unlocking of the door; a first switch detecting a state of the locking/unlocking member; a second switch switching between on and off of a room lamp of the vehicle; a connection portion to which a connector for an external device is connected; and a switch plate connecting at least the first switch and the second switch to the connection portion. Further, the switch plate includes a first switch plate connecting the first switch to the connection portion, a second switch plate connecting the second switch to the connection portion, and a switch-plate joining portion joining the first switch plate and the second switch plate together and passing between a bottom surface of a case and the locking/unlocking member.

Claims

1. A vehicle door lock device comprising:

a latch mechanism that engagingly holds a striker of a vehicle when a door of the vehicle is closed and that releases the striker when the door is to be open;

a locking/unlocking member that has a function related to switching between locking and unlocking of the door;

a first switch that detects a state of the locking/unlocking member corresponding to switching between locking and unlocking of the door;

a second switch that switches between on and off of a room lamp of the vehicle according to a turning position of a latch of the latch mechanism;

a connection portion that is located on an opposite side of the latch mechanism across the locking/unlocking member and to which a connector for connecting an external device is to be connected; and

a switch plate that electrically connects at least the first switch and the second switch to the connection portion, wherein

the switch plate includes

a first switch plate that is located on an opposite side of the latch mechanism across the locking/unlocking member and that electrically connects the first switch to the connection portion,

a second switch plate that is located on an opposite side of the first switch plate across the locking/unlocking member and that electrically connects the second switch to the connection portion, and

a switch-plate joining portion that joins the first switch plate and the second switch plate together passes between a bottom surface of a case, housing at least the locking/unlocking member and the switch plate, and the locking/unlocking member, and is interposed between the case and the locking/unlocking member.

2. The vehicle door lock device according to claim 1, wherein

the first switch plate includes a first-switch holding portion that holds the first switch, and

the second switch plate includes a second-switch holding portion that holds the second switch.

3. The vehicle door lock device according to claim 1, wherein

the locking/unlocking member includes a key member that performs an action related to switching between locking and unlocking of the door according to a lock/unlock operation with a key, and

the switch-plate joining portion passes between the bottom surface of the case and the key member and is interposed between the case and the key member.

4. The vehicle door lock device according to claim 2, wherein

the locking/unlocking member includes a key member that performs an action related to switching between locking and unlocking of the door according to a lock/unlock operation with a key, and

the switch-plate joining portion passes between the bottom surface of the case and the key member and is interposed between the case and the key member.
