- the support main body 62 When a load from the front side is input to the support main body 62, the support main body 62 tends to be displaced rearward. At this time, since the support member 60 is supported by the bumper RF20 in a cantilevered manner, the support member 60 rotates counterclockwise about the end surface 20B of the rear wall portion 24 of the bumper RF20 in a plan view (in the direction of arrow a in FIG. 1). Try to turn to. As a result, the fitting portion 72 of the support member 60 tends to be displaced forward, but the fitting portion 72 is fitted in the upper closed section 28A and the lower closed section 28C of the bumper RF20. The forward displacement of the portion 72 is limited by the front wall portion 22 of the bumper RF20.
- the rotation of the support member 60 is restricted, and the support member 60 supports the absorber side portion 44 and the pressure tube 52 from the rear side against the load from the front side.
- the absorber 40 is crushed in the front-rear direction (compressed and deformed), the pressure tube 52 is deformed (collapsed), and the pressure in the pressure tube 52 changes.

Specifically, when the load from the rear side inputted to the support main body 62 becomes a predetermined value or more, the rear surface 72A and the corner portion 72D of the fitting portion 72 are moved on the front surface of the rear wall portion 24 of the bumper RF20. It slides outward in the width direction and finally leaves the bumper RF20. Thereby, the fitting state of bumper RF20 and fitting part 72 is canceled, and support main-body part 62 is displaced to the front side (refer to Drawing 5B). When the bumper RF20 is further displaced rearward as the barrier B enters the rear side, the entire support member 60 is detached from the bumper RF20 (see FIG. 5C).

- the fitting length L1 of the fitting portion 72 with respect to the bumper RF20 is released with respect to the load from the rear side, and the sub radiator 94 is damaged. Can be suppressed or prevented. Therefore, even when the support member 60 is provided on the bumper RF 20 in order to expand the sensing range in the pedestrian collision detection sensor 50, it is possible to improve the damage ability for the sub radiator 94 with a simple configuration.
- the mounting mechanism portion 70 of the support member 60 has a contact portion 78 that contacts the end surface 20B of the rear wall portion 24 of the bumper RF 20.

Description
以下、図1~図5Cを用いて第1の実施の形態に係る歩行者衝突検知センサ50を備えた車両前部構造S1が適用された車両10(自動車)のフロントバンパ12について説明する。なお、図面において適宜示される矢印FRは車両前側を示し、矢印LHは車両左側(車幅方向一側)を示し、矢印UPは車両上側を示している。以下、単に前後、上下、左右の方向を用いて説明する場合は、特に断りのない限り、車両前後方向の前後、車両上下方向の上下、車両左右方向の左右を示すものとする。
図2に示されるように、バンパカバー14は樹脂製とされている。また、バンパカバー14は、車幅方向に延在されて、図示しない部分で車体に対し固定的に支持されている。さらに、バンパカバー14の車幅方向外側部分14Aは、平面視で車幅方向外側へ向かうに従い後側へ傾斜されて、車両10のコーナー部10Aを構成している。
図2に示されるように、バンパRF20はバンパカバー14の後側に配置されている。このバンパRF20は、車幅方向を長手方向とした中空の略矩形柱状に形成されて、車幅方向外側へ開放されている。また、バンパRF20は、アルミ系等の金属材料により構成され、押出成形等の手法によって製作されている。
図2に示されるように、アブソーバ40は、発泡樹脂材すなわちウレタンフォーム等によって構成されている。このアブソーバ40は、バンパカバー14とバンパRF20との間に設けられると共に、車幅方向を長手方向とした長尺状に形成され、バンパRF20の長手方向に沿って配置されている。具体的には、アブソーバ40は、アブソーバ40の車幅方向中間部分を構成するアブソーバ本体部42を有しており、アブソーバ本体部42は、バンパRF20の車幅方向中間部の前側に隣接して配置されている。また、アブソーバ40は、アブソーバ40の車幅方向外側部分を構成するアブソーバサイド部44を有しており、アブソーバサイド部44はバンパRF20の屈曲部30の前側に隣接して配置されている。
図2~図4に示されるように、歩行者衝突検知センサ50は「圧力センサ部材」としの圧力チューブ52を有している。圧力チューブ52は、長尺状に形成されると共に、断面略円環状の中空構造体として構成されている。また、圧力チューブ52の外径寸法は、アブソーバ40の保持溝部46の内径寸法に比べて僅かに小さく設定されており、圧力チューブ52の長手方向の長さは、アブソーバ40の長手方向の長さに比べて長く設定されている。そして、圧力チューブ52が保持溝部46内に組付けられている(嵌め込まれている)(図4参照)。なお、保持溝部46及び圧力チューブ52は、前述したバンパRF20の上側の被係合孔32に対して下側に配置されて、保持溝部46及び圧力チューブ52と被係合孔32とが平面視でラップしないように設定されている。
図2に示されるように、支持部材60は樹脂製とされている。また、支持部材60は、バンパRF20の屈曲部30の先端部にそれぞれ取付けられて、バンパRF20から車幅方向外側へ延出されている。すなわち、支持部材60は、バンパRF20に片持ちで支持されて、車両10のコーナー部10Aに対して後側にそれぞれ配置されている。そして、一対の支持部材60は、車幅方向において左右対称に構成されている。このため、以下の説明では、左側に配置された支持部材60について説明し、右側に配置された支持部材60についての説明は省略する。
図6を用いて第2の実施の形態に係る歩行者衝突検知センサ50を備えた車両前部構造S2について説明する。第2の実施の形態では、支持部材100の形態及び支持部材100のバンパRF20への取付構造を除いて第1の実施の形態と同様に構成されている。なお、以下の説明では、支持部材100において第1の実施の形態の支持部材60と同様に構成されている部分については同一の符号を付している。
図7を用いて第3の実施の形態に係る歩行者衝突検知センサ50を備えた車両前部構造S3について説明する。第3の実施の形態では、支持部材200の形態及び支持部材200のバンパRF20への取付構造を除いて第2の実施の形態と同様に構成されている。なお、以下の説明では、支持部材200において第2の実施の形態の支持部材100と同様に構成されている部分については同一の符号を付している。
