PROBLEM TO BE SOLVED: To reduce variations in collision detection accuracy which are caused by change of hardness of an absorber.SOLUTION: A front bumper 10 includes a bumper cover 12, an absorber 30 provided on the vehicle rear side of the bumper cover, a bumper RF 20 provided on the vehicle rear side of the absorber, and a pressure tube 52 provided between the absorber 30 and the bumper RF 20. The pressure tube 52 is compressed to be deformed between the absorber 30 and the bumper RF 20 before the absorber 30 and the bumper RF 20, which face each other in a vehicle fore and aft direction, contact with each other during a collision.SELECTED DRAWING: Figure 1
【課題】アブソーバの硬さ変化による衝突検知精度のばらつきを低減する。【解決手段】フロントバンパ10は、バンパカバー12と、当該バンパカバーの車両後側に設けられるアブソーバ30と、当該アブソーバの車両後側に設けられるバンパRF20と、アブソーバ30とバンパRF20の間に設けられる圧力チューブ52と、を備え、衝突時に、車両前後方向で対向するアブソーバ30とバンパRF20が接触する前に、圧力チューブ52がアブソーバ30とバンパRF20との間で圧迫されて変形する。【選択図】図1
