<p>PURPOSE:To secure the switching of the operating condition by providing a cancel means, which is moved by the key operation, in a lock cancel member, and stitching the operating force to the lock cancel means to a transmission position and a non- transmission position. CONSTITUTION:A lock mechanism 11, which consists of a hook 17 and a ratchet 18, and a striker 13 to be fitted/disconnected in/from the lock mechanism 11 are provided. Next, a lock cancel mechanism 9, which consists of an open lever 21 for cancelling the lock of the lock mechanism 11 and an operating force transmitting cable lever 22, is provided. Next, a cancel cable 25 is locked with one end of the operating force transmitting cable lever 22, and a bent part 27a of a cancel rod 27 is locked with a guide groove 21 provided in the open lever 21. The cancel cable 25 is pulled to make a pushing part 22c for engagement of the operating force transmitting cable lever 22 push the bent part 27a, and the open lever 21 and the lock mechanism 11 work together to cancel the lock. Furthermore, in the case of securing the cancel condition, a key device 6 is operated to move the bent part 27a to the upper end of a groove 21d, and the pushing part 22c is made to be under the idle condition at the time of cancelling the lock. Switching from the ordinary operation condition to the cancel condition can be thereby secured.</p> |
