To achieve a pipe holding structure which protects a peripheral member by controlling a direction of movement of a bracket fixed to a pipeline and a pipeline at rear collision of a vehicle.SOLUTION: A pipe holding structure comprises a fuel-tank 12, a rear axle 14 which is provided on rear of the fuel-tank 12, a pipeline 16 which is provided between the fuel-tank 12 and the rear axle 14 in a cross direction and a first bracket 18 and a second bracket 20 which are fixed to the pipeline 16. The first bracket 18 includes a bent part 18c which bends so that a front end part 18a is disposed in lower side than a rear end part 18b. The front end part 18a is disposed between a floor panel 22 and the fuel-tank 12 below it in a vertical direction. The second bracket 20 is provided on a rearward direction of the first bracket 18 and moreover is high in rigidness. When rear of the vehicle is collided, the first bracket 18 bends at the bent part 18c and the second bracket 20 rotates the front end part 20a as a fulcrum.SELECTED DRAWING: Figure 3
【課題】車両後突時、配管および配管に固定されるブラケットの移動方向を制御することで周辺部材を保護する配管保持構造を実現する。【解決手段】配管保持構造は、燃料タンク12と、前記燃料タンク12後方に設けられるリアアクスル14と、前後方向で前記燃料タンク12と前記リアアクスル14との間に設けられる配管16と、前記配管16に固定される第一のブラケット18および第二のブラケット20と、を備え、前記第一のブラケット18は、後端部18bよりも前端部18aが下側に配置され屈曲部18cを有し、前記前端部18aは、上下方向で前記フロアパネル22とその下方の前記燃料タンク12との間に配置され、前記第二のブラケット20は、前記第一のブラケット18よりも後方に設けられ、かつ、剛性が高く、後突時に、前記第一のブラケット18は、前記屈曲部18cで折れ曲がり、前記第二のブラケット20は、前端部20aを支点に回転する。【選択図】図3
