Abstract

A fastening structure ( 10 ) includes: a resin member ( 14 ) that contains a resin material, and that has a through-hole ( 14 H) for mounting having a tapered inner wall surface ( 14 T); a member for fastening ( 16 ) that is made of metal, and that has a collar portion ( 16 C) that is inserted within the through-hole ( 14 H) for mounting and whose intermediate portion has a tapered outer wall surface ( 16 T) that abuts the tapered inner wall surface ( 14 T), and a flange portion ( 16 F) that projects out along an obverse face of the resin member ( 14 ) at an end portion ( 16 Z) at a large-diameter side of the collar portion ( 16 C); and an adhesive ( 18 ) that is provided between the obverse face ( 14 A) of the resin member and the flange portion ( 16 F), and that adheres the resin member ( 14 ) and the member for fastening ( 16 ).

First claim

The invention claimed is:

1. A fastening structure, comprising:
a resin member that contains a resin material, and that has a through-hole for mounting having a tapered inner wall surface whose diameter decreases from an obverse face toward a reverse face of the resin member;
a fastened-to member that is disposed to face the resin member;
a member for fastening that is made of metal, and that has a collar portion that is inserted within the through-hole for mounting and that includes an intermediate portion having a tapered outer wall surface configured to directly contact the tapered inner wall surface, and a flange portion that projects out along the obverse face of the resin member at an end portion at a large-diameter side of the collar portion, an end portion at a small-diameter side of the collar portion projecting out further than the reverse face of the resin member and abutting the fastened-to member;
an adhesive that is provided between the obverse face of the resin member and the flange portion, and that adheres together the resin member and the member for fastening; and
a fastener that produces a fastening load applied to the fastened-to member and the member for fastening and not applied to the resin member and the adhesive.

2. The fastening structure of claim 1 , wherein the through-hole for mounting includes:
a tapered hole that has the tapered inner wall surface and that is formed from the obverse face of the resin member toward the reverse face; and
a through-hole that is connected to a small-diameter side of the tapered hole and that passes through to the reverse face of the resin member and whose inner wall surface is a cylindrical surface.

3. The fastening structure of claim 1 , wherein the adhesive is only provided between the obverse face of the resin member and the flange portion.
