A molded body 26 is inserted as a partition member extending in the vehicle width direction. The molded body 26 includes a vertical wall 26a that divides the hollow portions 21a to 21c into substantially right and left parts, and horizontal walls 26b and 26c that divide the hollow parts 21a to 21c (vertical wall 26a) into substantially three parts in the vertical direction. And a constant cross section having a substantially square shape. The formed body 26 divides the hollow portions 21a to 21c in the linear portion 22 into a plurality of (six) rooms C1 to C6 that penetrates in the vehicle width direction.

本実施形態では、中空部２１ａ，２１ｂにおいて、部屋Ｃ１，Ｃ３，Ｃ４，Ｃ６には、発泡充填材としての固体の加熱発泡材Ｍ（図４参照）を熱処理により発泡させてなる発泡材２７が充填されている。また、中空部２１ｃにおいて、部屋Ｃ１〜Ｃ３，Ｃ４，Ｃ６には、同様の発泡材２７が充填されている。つまり、発泡材２７は、前記成形体２６により各中空部２１ａ〜２１ｃを区画した部屋Ｃ１〜Ｃ６に小分けして供給される加熱発泡材Ｍが発泡されて当該部屋Ｃ１〜Ｃ６に充填される。そして、前記バンパリインホース１６は、各中空部２１ａ〜２１ｃの対応する部屋Ｃ１〜Ｃ６に発泡材２７が充填されることで補強される。各中空部２１ａ〜２１ｃ（部屋Ｃ１〜Ｃ６）における発泡材２７の配置は、バンパリインホース１６に要求される強度・性能に最適となるように調整されている。   In the present embodiment, in the hollow portions 21a and 21b, in the chambers C1, C3, C4, and C6, a foamed material 27 formed by foaming a solid heated foamed material M (see FIG. 4) as a foaming filler by heat treatment is provided. Filled. In the hollow portion 21c, the chambers C1 to C3, C4, and C6 are filled with the same foam material 27. That is, the foamed material 27 is filled with the foamed material 26 by heating the foamed material M which is supplied in small portions to the rooms C1 to C6 in which the hollow portions 21a to 21c are partitioned. The bumper-in hose 16 is reinforced by filling the corresponding rooms C1 to C6 of the hollow portions 21a to 21c with the foam material 27. The arrangement of the foam material 27 in each of the hollow portions 21a to 21c (rooms C1 to C6) is adjusted so as to be optimal for the strength and performance required for the bumper-in hose 16.

ここで、車両の衝突等により前方から衝撃が加えられると、この衝撃は、バンパリインホース１６及びクラッシュボックス１３を介してサイドメンバ１１（ボデー）に伝達される。このとき、バンパリインホース１６とともにクラッシュボックス１３が塑性変形することで、ボデーへと伝達される衝撃を緩衝する。これにより、ボデー及び乗員に加えられる衝撃エネルギーが吸収される。   Here, when an impact is applied from the front due to a vehicle collision or the like, the impact is transmitted to the side member 11 (body) via the bumper-in hose 16 and the crash box 13. At this time, the impact box transmitted to the body is buffered by the plastic deformation of the crash box 13 together with the bumper-in hose 16. Thereby, the impact energy applied to the body and the passenger is absorbed.

特に、上述の態様で発泡材２７の充填されたバンパリインホース１６は、車両幅方向中央部でのいわゆるポール衝突を想定した３点曲げ評価において優れていることが確認されている。図３は、バンパリインホースの変形量（ストローク）に対する荷重の推移を示すグラフである。同図において、発泡材２７の充填されたバンパリインホース１６の荷重の推移を実線で、発泡材２７の充填されないバンパリインホース、即ちバンパリインホース本体２１単独の荷重の推移を破線でそれぞれ示す。同図から明らかなように、発泡材２７の充填されたバンパリインホース１６では、荷重の大きさを所定の範囲に収めつつ、効率的に衝突エネルギーが吸収されて、最大ストロークが抑制されていることが確認される。   In particular, it has been confirmed that the bumper-in hose 16 filled with the foam material 27 in the above-described manner is excellent in the three-point bending evaluation assuming a so-called pole collision at the center in the vehicle width direction. FIG. 3 is a graph showing the transition of the load with respect to the deformation amount (stroke) of the bumper inhose. In the figure, the transition of the load of the bumper in hose 16 filled with the foam material 27 is indicated by a solid line, and the transition of the bumper in hose not filled with the foam material 27, that is, the load of the bumper inhose body 21 alone is indicated by a broken line. Each is shown. As is clear from the figure, in the bumper-in hose 16 filled with the foam material 27, the collision energy is efficiently absorbed and the maximum stroke is suppressed while keeping the magnitude of the load within a predetermined range. It is confirmed that
