It is a conventional general technique to lock the piece 2 'on the outer surface side of the sandwiching portion 4'. However, this has a problem that the spring 71 may be hard so as to obtain a sufficient clamping action, and it is troublesome to assemble the spring 71. Therefore,
For example, as shown in FIG. 5C, the spring hole 72 is made longer, and a guide groove 73 is provided between the spring hole 72 and a locking portion 74 for locking the locking end portion 71 a of the spring 71. Have been. According to this, the spring 71 can be easily assembled by pushing the spring 71 along the guide groove 73. However, in such a structure, when a hanging strap S 'or the like is attached to the spring 71 and the laundry pinch 1' is used in a suspended state, for example, it is used in such a manner that the laundry held by the clothespin is pulled and taken. When taking an aspect or suspending a heavy object, there is also a disadvantage that the spring 71 comes off so as to come off from the pinch piece 2 ', and the clothespinch 1' may be disassembled.
