Description of the Related Art In order to attach a small and lightweight member 13 to a relatively large structure 11 constituting a side plate or a casing of a resin member such as a developing device or a process cartridge of an image forming apparatus, an exploded view of FIG. The tapping screw 15 is used as shown in the fastening diagram of FIG. 15 and FIG. 15, and the resin structure is particularly shown in the exploded view of FIG. 16 and the fastening diagram of FIG. A metal screw 3A is embedded in the body 11 by an insert during molding. In the case of the former type in which the tapping screw 15 is used, the tapping screw 15 is repeatedly removed and replaced to replace the attached member 13, so that the screw hole is broken by the tapping screw 15 and cannot be tightened. For this reason, the structure 11 constituting the side plate, the casing, and the like, which are members made of the resin, cannot be reused, and it is necessary to replace the structure with a new part. When a resin member embedded with the latter metal screw 3A inserted is used, it is necessary to remove the metal screw 3A when disassembling the side plate or casing, which is the resin member, for recycling. There is.

なくてはならなくなったりする。Replacing a considerably large structure 11 constituting a side plate, a casing, or the like in which the screw holes of the self-tapping screws have collapsed due to the collapse of the tapping screws requires a lot of trouble and cost, and most parts are still required. Even though the screw hole can be used, the screw hole has to be destroyed and it has to be discarded and recycled only for raw materials.

A small resin member with a prepared hole for tapping screws is press-fitted into a relatively large structure, and other members are fastened with tapping screws. However, in order to replace it, a small resin member having a new pilot hole for tapping screws is set by removing the resin member that has been loosened from the screw portion by applying pressure in a direction opposite to the press-fitting direction. Thus, it is possible to easily restore to a new functional state. The resin member, which is a replacement part, is fitted to a boss appropriately provided inside a relatively large structure of the image forming apparatus, so that it can be easily extracted and handled when necessary, which is convenient.
