Piping retaining structure

Abstract

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

Claims

[Claim 1] A fuel tank located below the floor panel in the vertical direction of the vehicle, A rear axle is provided behind the fuel tank in the longitudinal direction of the vehicle, A pipe provided between the fuel tank and the rear axle in the longitudinal direction of the vehicle, A first bracket and a second bracket, both fixed to the aforementioned piping and supporting the piping to the vehicle, Equipped with, The first bracket is, Extending in the longitudinal direction of the vehicle, It has a crank shape with a bent section that bends so that the front end is positioned lower than the rear end. The aforementioned front end is positioned between the floor panel and the fuel tank in the vertical direction of the vehicle. The second bracket is, It is located behind the first bracket, It has higher rigidity than the first bracket mentioned above. During a rear-end collision of the vehicle, the first bracket bends at the bend, and the second bracket rotates with its front end as the pivot point. A pipe holding structure characterized by the following features.
