To provide a pedestrian protection device that is able to obtain an appropriate reaction force according to the height of a pedestrian without changing the entire length when actuation takes place.SOLUTION: A reaction force applied to a pedestrian P from a grill 120 is adjusted by a reaction force adjustment mechanism 30 so as to become greater in a case where the height of a pedestrian P is larger than a predetermined value a than a case where the height of the pedestrian P is smaller than the predetermined value a. Therefore, in a case where the height of the pedestrian P is shorter than the predetermined value a, that is, in a case of a pedestrian P1 comparatively small in body type and comparatively less in bearing force like a child or the like, a reaction force applied to the pedestrian P from the grill 120 can be made comparatively less. In a case where the height of the pedestrian P is higher than the predetermined value a, that is, in the case of a pedestrian P2 comparatively large in body size and comparatively great in bearing force like an adult or the like, the reaction force applied to the pedestrian P from the grill 120 can be made comparatively great.SELECTED DRAWING: Figure 1
【課題】作動時に車両の全長を変えることなく、歩行者の身長に合わせて適切な反力を得ることができる歩行者保護装置の提供。【解決手段】グリル120からの歩行者Pへの反力が、歩行者Pの身長が所定値aよりも小さい場合に比べて、歩行者Pの身長が所定値aよりも大きい場合に大きくなるよう、反力調節機構30によって調節される。そのため、歩行者Pの身長が所定値aよりも小さい場合、すなわち子供など比較的小柄な体格であり耐力が比較的小さい歩行者P1の場合には、グリル120からの歩行者Pへの反力を比較的小さくでき、歩行者Pの身長が所定値aよりも大きい場合、すなわち大人など比較的大柄な体格であり耐力が比較的大きい歩行者の場合P2には、グリル120からの歩行者Pへの反力を比較的大きくできる。【選択図】 図1
