While protruding into the large diameter hole 9a on the main body 2 side,
The movable portion 3 is in a state of protruding from the rear portion of the main body portion 2 in the direction opposite to the main body portion 2. Therefore, when the resin molded body 1 is formed into a product shape as shown in FIGS. 1B and 7, for example, the movable portion 3 is pressed while the main body portion 2 is pressed.
Is pressed in the direction of the arrow in FIG. 7, that is, upward. Then, in the movable portion 3, the shaft portion 10 moves from the large diameter hole 9a to the locking hole portion 9
It is moved so that it is forcedly passed through c to be dropped into the small diameter hole 9b, and is fitted. Once fitted into the small diameter hole 9b, the shaft portion 10 is prevented from being inadvertently moved to the large diameter hole 9a side due to the existence of the locking hole portion 9c. As a result, the movable portion 3 is assembled to the main body portion 2 with the shaft portion 10 as a pivot fulcrum.

Be assembled into. Therefore, the size of the small-diameter hole is not restricted during molding due to the relationship with the shaft portion, and can be set to a value with which the shaft portion can be fitted accurately. As a result, it is possible to obtain highly accurate fitting in the product shape, and it is possible to eliminate rattling of the movable portion. As described above, according to the present invention, the backlash of the movable portion can be structurally eliminated, so that the quality of applicable products can be improved and applicable products can be expanded.
