PROBLEM TO BE SOLVED: To provide a joint structure of a member for a vehicle and a joint method of the member for the vehicle which can maintain a joint state of a metal member and a resin member at the time of heating while suppressing thermal distortion caused by a difference in linear expansion of the metal member and the resin member, in a structure in which the metal member and the resin member are joined to each other by an adhesive.SOLUTION: A joint structure of a member for a vehicle has an adhesive which is provided between a metal member 22 and a resin member 12, joins both of the members and has a lower elastic modulus than those of the metal member 22 and the resin member 12, where a fastening member 32 fastening the metal member 22 and the resin member 12 is inserted therethrough, and an area S1 of a region where the metal member 22 and a second head part 32B overlap with each other when being viewed in an axial direction of the fastening member 32 is larger than an area S2 of a region where the resin member 12 and a first head part 32A overlap with each other when being viewed in the axial direction of the fastening member 32.SELECTED DRAWING: Figure 4
【課題】接着剤によって金属部材と樹脂部材とが接合された構造において、金属部材と樹脂部材との線膨張差による熱ひずみを抑制しつつ、加熱時に金属部材と樹脂部材との接合状態を良好に維持することができる車両用部材の接合構造及び車両用部材の接合方法を得る。【解決手段】金属部材22と樹脂部材12との間に設けられて両者を接合すると共に、金属部材22及び樹脂部材12よりも弾性率が低い接着剤を有し、金属部材22と樹脂部材12とを締結する締結部材32が挿通されており、締結部材32の軸方向から見て樹脂部材12と第1頭部32Aとが重なる領域の面積S2よりも、締結部材32の軸方向から見て金属部材22と第2頭部32Bとが重なる領域の面積S1の方が大きい。【選択図】図4
