ABSTRACT:
When an open lever assumes a position causing a latching member to release a striker, an arm portion of the open lever intersects a travelling path of a key cylinder-actuated lever which is synchronously pivotal with a locking knob-actuated lever. Thus, when the door is opened, the locking knob can not be shifted to its locking position thereby suppressing a so-called "keyless locking".
