<p>PURPOSE:To hold an unlocked state for a smooth operation for automatically opening and closing the door by pulling cable through the operation of a door- engine-side changeover lever when switching the door from a position where it is manually opened and closed to a position where it is automatically operated by a door engine. CONSTITUTION:To automatically open or close the door using an door engine 13, a changeover lever attached to the door engine 13 is switched from a manual position H to an automatic position A to pull cable 23. Then a hook 23b at the end of the wire of the cable 23 moves downwards and pushes down a fixed member 21 a fixed to a rod, thus undoing a lock 14b. This state is maintained to prevent the door 12 from colliding against a striker 18 when opened by the door engine 13. Thus when the door 12 is automatically opened or closed by the door engine 13, the lock is smoothly and readily undone, while the door 12 can be opened and closed manually by switching only an operating lever.</p> |
