Abstract
A door member locking/unlocking apparatus comprises a motor for driving an output shaft rotationally, and a latch rotatably hinged in a position to engage with a striker for retaining a door member in a closed state and urged in a direction to disengage from the striker. A first ratchet regulates the latch in a partially latched position and in a fully latched position. A second ratchet turns the latch from the partially latched position to the fully latched position. An engaging pin provided on the first ratchet releases the retention of the latch in the fully latched position by the first ratchet. A cam is arranged to have an axis of rotation in parallel with that of the latch. The cam is rotationally driven by the motor for actuating the second ratchet and the engaging pin.
