ABSTRACT:
A locking lever of a door latch can be operated either manually by operating a lock knob or electrically by applying a current to an electrically operating mechanism. The turning force of the mechanism is transmitted to the lever via a first oscillatory member and second one cooperative loosely with the first member. The second member operates to shift the lever to a lock or an unlock position after it has been turned by the first member by a prescribed angle. The first member energizes a return spring, the biasing force of which returns the first member to neutral position when the current to the mechanism is interrupted. The lock knob can be operated lightly since the mechanism with the first member at the neutral position does not obstructs the knob.
