PROBLEM TO BE SOLVED: To provide a vehicular collision sensor fitting structure capable of reliably and stably sensing collision with a pedestrian or the like and precisely discriminating the collision with the pedestrian or the like and the other small collision while securing a collision energy absorption amount for protecting the pedestrian.SOLUTION: A shock absorption member 4 arranged between a bumper face 2 and a bumper beam 3 includes: an upper rear surface 11 and a lower rear surface 12 which are opposite to the bumper beam 3; a protruded part upper surface 16 which continues with a lower edge of the upper rear surface 11 and is extended to the front side; a protruded part lower surface 17 which continues with an upper edge of the lower rear surface 12 and is extruded to the front side; and a protruded part front surface 18 which continues with front edges of the protruded part upper surface 16 and the protruded part lower surface 17. Therein, the protruded front surface 18 is formed of a groove part 20 into which a collision sensor 5 is fitted, difference parts 24, 25 are formed on the neighborhood of upper and lower edges of the protruded part front surface 18 and bent portions 30, 31 which join the protruded part front surface 18 with the protruded part upper surface 16 or the protruded part lower surface 17 are respectively located on the rear side rather than the groove part 20.SELECTED DRAWING: Figure 1
【課題】歩行者保護のための衝突エネルギ吸収量を確保しつつ、歩行者等との衝突を高信頼且つ安定的に感知することができ、且つ歩行者等との衝突とその他の小衝突とを高精度に判別可能な車両用衝突感知センサ取付構造を提供する。【解決手段】バンパフェイス2とバンパビーム3との間に配設される衝撃吸収部材4は、バンパビーム3に対向する上部後面11及び下部後面12と、上部後面11の下端と連続して前方に延在する凸部上面16と、下部後面12の上端と連続して前方に延在する凸部下面17と、凸部上面16及び凸部下面17の前端と連続する凸部前面18と、を具備し、凸部前面18には、衝突感知センサ5が嵌め込まれる溝部20が形成され、凸部前面18の上下端の近傍には段差部24、25が形成され、凸部前面18と凸部上面16若しくは凸部下面17とをつなぐ曲折部30、31は、夫々溝部20よりも後方に位置する。【選択図】図1
