PROBLEM TO BE SOLVED: To provide a hook part structure which allows hooking even when a hook position is in a low position.SOLUTION: An extension piece 61 extending from a body 2 is provided on a rear surface construction member 13 forming the body 2. A folding part 71 which folds the extension piece 61 toward the body 2 side in a state that folding back is possible, is provided on a stem of the extension piece 61. A free end of the extension piece 61 is separated from the body 2 for forming a hooking space 101 between the extension piece 61 and the body 2. In the state, rotation of the extension piece 61 in a direction separating from the body 2 is inhibited by an inhibition piece 31, and a hook shape is formed by the extension piece 61 and the rear surface construction member 13 forming the body 2. |
