ABSTRACT:
A structure for fastening a resin member to a base member typically composed of a metallic material with a threaded bolt passed through holes provided in the resin member and the base member, comprising a metallic sleeve through which the bolt is passed fitted in the hole of the resin member, the length of the sleeve being slightly shorter than that of the hole of the resin member. Therefore, when the threaded bolt is tightened, the inner circumferential wall of the hole of the resin member collapses upon a longitudinal end of the sleeve so that the threaded bolt may be securely tightened without damaging the resin member because the metallic sleeve bears a substantial amount of the stress produced by the fastening of the threaded bolt. Further, intervention of the part of the inner circumferential wall of the hole of the resin material between the longitudinal end of the sleeve and the head of the threaded bolt or a washer thereof prevents metal-to-metal contact therebetween, and produces a vibration insulating effect.
