Abstract
A door open/close detector is incorporated in a door lock device. The door lock device includes a case, a latch plate pivotally connected to the case to pivot between a latch position to latch a striker and an open position to release the striker, and a lock plate pivotally connected through a shaft to the case to pivot between a lock position to lock the latch plate in the latch position and an unlock position to unlock the latch plate. The door open/close detector includes a switch connected to the case. The switch includes a given surface and a detecting pin. The detecting pin is axially movable in both directions thereby to cause a head thereof to be retractable into and protrusible from the given surface. The detecting pin turns the switch ON and OFF in response to the axial movement thereof. An actuating lever is connected to the lock plate to pivot therewith and has a pin actuating portion. The pin actuating portion is slideable on the give surface while it is pressed against the same thereby to actuate the head of the detecting pin when the lock plate is pivoted about the given shaft between the lock and unlock positions.
