PURPOSE:To securely and easily release a hook by providing a protrusion at an elastic part of a hook and also providing a guide member for a working member inserted from a hole equipped near the root of the hook to move straight and by inserting straight the protrusion provided at the elastic part of the hook into a path of the working member inserted from the hole. CONSTITUTION:When a working member 16 is inserted from a prolonged hole 6 of a door 1 under the condition that hanging parts 2b, 3b of hooks 2, 3 are connected to beams 14, 15 of the fitting part 10 of a case 9, the working member 16 moves straight to the arrow B direction along the upper face of guide faces 7a, 7b of a guide plate 7 ad the upper faces of elastic parts 2a, 3a of the hooks 2, 3. And then the front of the working member 16 contacts the slanting faces 4a, 5a of the protrusions 4, 5 provided at the elastic parts 2a, 3a of the hooks 2, 3 respectively. Next, further, when the working member 16 is inserted, the front thereof slides on the slanting faces 4a, 5a of the protrusions 4, 5 and the elastic parts 2a, 3a of the hooks 2, 3 are elastically deformed. In this way, the connection of the hanging parts 2b, 3b and the beams 14, 15 is released to open the locking. |
