ABSTRACT:
In a door-locking device, an output lever is connected to a release member and other operating mechanisms in order to eliminate a locking lever and a locking link. The elimination of these members decreases the number of connecting portions between members or mechanisms, thereby decreasing loose fittings therebetween. Thus, the generation of noise is lowered resulting in the realization of quietude. Also, the sense of operation of the door-locking device is more comfortable due to the decreased feeling of looseness.
