Vehicle door lock device

Abstract

Abstract A vehicle door lock device has a synthetic resin made body and a back plate attached on the rear side of the body. A lock lever is journalled between the back plate and the body in order to change-over the lock device between its locked condition and unlocked condition. A plastic made actuator box containing a power source for powerfully changing-over the lock lever is placed below the body. A switch box is formed at a rear side of the box and a switch body is contained in the switch box. A rotation shaft of the switch body protrudes rearward through the switch box and a switch arm is secured to the protruded portion of the rotation shaft. At the overlap position of the connecting lever and the lock lever, the connecting lever is installed rotatably, one end of the lever being connected to the switch arm and another end of it being connected to the key cylinder of a door or the lock lever. The switch body is electrically connected to the lock devices of other doors, functions co-operatively motion of the key cylinder or lock lever, and sends out control signal for changing-over the lock devices of the other doors between their locked condition and unlocked condition. The switch box is installed at a position where it is not overlapped with the lock lever. The switch box has a circumferential wall protruded integrally from the actuator box and a lid formed separately from the actuator box, and the bottom plate of the actuator box is used simultaneously as an outer wall of the actuator box. The lid of the actuator box is even with the back plate or higher than the back plate outward.
