Abstract
Official abstract text for this publication.
A vehicle member joining structure has: a metal member that is part of a vehicle; a resin member that is adjacent to the metal member; and an adhesive that is provided between the metal member and the resin member and joins the metal member to the resin member, the adhesive having an elastic modulus that is lower than elastic moduli of the metal member and the resin member, wherein, given that (i) ΔL is a difference in linear expansions of the metal member and the resin member at a time of heating in a drying process after application of the adhesive, (ii) T 0 is a thickness of the adhesive and (iii) T 1 is a length of an end surface of the adhesive, the following predetermined relational expression is satisfied T 1 2 =T 0 2 +ΔL 2 .
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle member joining structure comprising: a metal member that is part of a vehicle; a resin member that is adjacent to the metal member; and an adhesive that is provided between the metal member and the resin member and joins the metal member to the resin member, the adhesive having an elastic modulus that is lower than elastic moduli of the metal member and the resin member, wherein a first through-hole is formed in the metal member, and a second through-hole is formed in the resin member coaxially with the first through-hole, a fastening member that fastens the metal member and the resin member together is inserted through the first through-hole and the second through-hole, a gap between a shaft of the fastening member and an inner periphery of at least one of the first through-hole and the second-through hole is larger than a difference in linear expansions of the metal member and the resin member at a time of heating of the vehicle member joining structure in a drying process of the adhesive, the fastening member has (1) a first head that extends along the resin member from a first end of the shaft and anchors on the resin member, and (2) a second head that extends along the metal member from a second end of the shaft and anchors on the metal member, and a surface area of a first region at which the metal member and the second head overlap as seen from an axial direction of the fastening member is larger than a surface area of a second region at which the resin member and the first head overlap as seen from the axial direction of the fastening member. 2. The vehicle member joining structure of claim 1 , wherein the adhesive is provided between the shaft and the metal member and between the shaft and the resin member. 3. The vehicle member joining structure of claim 1 , wherein the metal member is a cross member inner of the vehicle. 4. The vehicle member joining structure of claim 1 , wherein the metal member is a rocker inner panel of the vehicle.
