To obtain a connection structure of a vehicle tubular member which enables improvement of performance of absorbing a load from the radial outer side for a connection portion connecting a first tubular member with a second tubular member.SOLUTION: An insertion part 18 of a second tubular member 14 is formed with multiple contact parts 20 which are placed in contact with an inner periphery part of a first tubular member 12. Further, a valley folded part 22 is formed between the contact parts 20 located adjacent to each other in a circumferential direction of the second tubular member 14. When a load from the radial outer side of the first tubular member 12 is transmitted to the insertion part 18 through the first tubular member 12, the insertion part 18 starts deformation from the valley folded parts 22. The insertion part 18 is deformed in this way to absorb a part of the load.SELECTED DRAWING: Figure 3

    【課題】第1管状部材と第2管状部材との連結部分に対し、径方向外側からの荷重の吸収性能を向上できる車両用管状部材の連結構造を得る。【解決手段】第2管状部材14の挿入部18には、第1管状部材12の内周部に当接される複数の当接部20が形成され、更に、第2管状部材14の周方向に互いに隣り合う当接部20の間に谷折部22が形成される。第1管状部材12の径方向外側からの荷重が第1管状部材12を介して挿入部18に伝わると、挿入部18は、谷折部22から変形が開始される。このようにして挿入部18が変形されることで、荷重の一部を吸収できる。【選択図】図3
