PROBLEM TO BE SOLVED: To provide a hook capable of smoothly performing the locking to or release from a fixing structure.SOLUTION: A stopper 6 turns between a closing position closing a hook opening and an opening position opening the same around a pin 9. A handle 10 turns between an outermost side position and an innermost side position around a pin 11. The handle and the stopper are connected by means of a guide groove 12 of the handle and a guide pin of the stopper projecting into the guide groove. When the stopper is disposed at the closing position and the handle is disposed at a first position, the guide pin 13 is positioned at a first portion 12a of the guide groove and the stopper is locked at the closing position. A first spring 14 energizes the stopper toward the closing position, and a second spring 15 energizes the handle toward the outermost side position. When the handle turns from the locking position of the stopper to the innermost side position, the guide pin enters from the first portion into a second portion 12b of the guide groove and the stopper turns to the opening position.SELECTED DRAWING: Figure 1 |
