PROBLEM TO BE SOLVED: To reduce the number of parts of, for example, an auto-lock mechanism to simplify its structure.SOLUTION: An auto-lock mechanism A is configured such that when causing a hook lever 2 to fall, a lock unit 5 is operated using a key in the locking direction to rotate an operation lever 44 in the same direction, a cam-shaped engagement guide of the operation lever 44 causes rear and tip end portions of a lock lever 4 to rotate in lower and upper directions, respectively, to provide a locked position, the hook lever 2 is brought into rotation in a fall direction from the locked state to a main body 1 while pressing down a tip end side of the lock lever 4 by a lower end portion of the hook lever 2, and the urging force of a spring member 43 causes the tip end of the lock lever 4 to return to the locked position in an elastic manner.SELECTED DRAWING: Figure 3
【課題】オートロック機構などの部品点数を少なくし、構造を簡単にする。【解決手段】オートロック機構Ａは、フックレバー２を倒伏させる際に、鍵により錠前ユニット５を施錠方向に操作して作動レバー４４を同方向に回動し、作動レバー４４のカム形状の係合案内により、ロックレバー４の後端部を下方向に先端部を上方向にロック位置まで回動し、この施錠状態から、フックレバー２を倒伏方向に回動させ、フックレバー２の下端でロックレバー４の先端部側を押し下げつつ、本体１に倒伏し、ロックレバー４の先端部をバネ部材４３の付勢力によりロック位置に弾性復帰させる形式を取る。【選択図】図３
