部材に確実に取り付ける手段を講じることができる。The contraction of the bush body made of synthetic resin is restricted by the shape-retaining member, which prevents the bush body from contracting and clinging to the shaft. The material of the shape-retaining member is preferably metal. In addition, since a part of the shape-retaining member is exposed from the bush body surface and a mounting structure such as a screw is provided on this exposed surface part, measures must be taken to securely attach the bush to the mounting member with a minimum number of parts. You can

埋設される。Further, a portion (6) of which the surface is exposed from the bush body (1 ′) is provided on the outer peripheral portion of the shape-retaining member (5). As shown in FIG.
A male screw portion (7) and a flange portion (8) for attaching the bush (1) to the housing (2) are provided. A female screw portion (9) is provided in advance in the opening of the shaft hole (3) of the housing (2) corresponding to the male screw portion (7). A large number of through holes (11) are formed in the embedded portion (10) of the shape-retaining member (5) in order to strengthen the connection between the embedded portion (10) and the bush body (1 '). However, as shown in FIG. 3, instead of providing the through hole (11), the embedded portion (10) is enlarged to increase the joint area, whereby the embedded portion (10) and the bush body ( It is also conceivable to strengthen the connection of 1 '). The shape-retaining member (5) is embedded in the bush body (1 ') when the bush body (1') is molded.
