A retracting device includes a retracting main body (6) including a hook (2) disposed in a case (1), an urging member (5), and a braking device (3); and a protruding portion (9) placed on a moving body side. In the retracting device, the hook is switched between a retracting position which allows a moving body (8) to move in an engagement state with the protruding portion (9), and a standby position which comes to be immobile in an engagement released state. The braking device (3) includes a piston damper having a cylinder (30) and a piston rod (32), and either one of the cylinder (30) or the piston rod (32) is fixed in the case (1), and the other is slidably disposed and is pivotally supported on an end side to be capable of turning the hook (2). The hook (2) is provided to come to the standby position which is disengaged from the protruding portion (9) in a state wherein the piston rod (32) is sheathed, and has reduced a protruding dimension, and to be switched to the retracting position from the standby position when the piston rod (32) increases the protruding dimension. |
