Abstract:
An electric door lock includes a door latch mechanism movable between latching and unlatching positions, a manual operation mechanism, and first and second rotatable members. The manual operation mechanism is manually operable to drive movement of the door latch mechanism between the latching and unlatching positions. The first rotatable member is rotatable about an axis, and includes a rotary body and a clutch mechanism. The clutch mechanism is disposed resiliently on the rotary body and is movable parallel to the axis toward and away from the rotary body. The second rotatable member is coupled to the manual operation mechanism for co-rotation therewith, and has one side that confronts the first rotatable member and that is provided with a pushed unit.
