To provide a vehicle body side structure having an impact absorbing member capable of increasing impact energy absorbing amount while adopting a structure for promoting axial collapse.SOLUTION: A side sill 5 provided on a side part of a vehicle body so as to extend in the longitudinal direction of the vehicle body and a shock-absorbing member 6 provided inside the side sill 5 are provided. The shock absorbing member 6 includes a plurality of cylindrical parts 21 arranged in the front-rear direction in the side sill 5, and a plurality of connecting parts 22 connecting the cylindrical parts 21. The cylindrical part 21 is formed into a cylindrical shape having a polygonal cross-section by a plurality of square ridges 25 extending in the vehicle width direction and a plurality of plate parts 26 adjacent to each other via the square ridges 25. A fragile part 27 is formed which is partially less rigid in an outer end in the vehicle width direction of at least one of the plurality of plate parts 26.SELECTED DRAWING: Figure 2
【課題】軸圧壊が促進される構造を採りながら衝撃エネルギー吸収量を増やすことが可能な、衝撃吸収部材を有する車体側部構造を提供する。【解決手段】車体の側部に車体の前後方向に延びるように設けられたサイドシル5と、サイドシル5の内部に設けられた衝撃吸収部材6とを備える。衝撃吸収部材6は、サイドシル5内で前後方向に並ぶ複数の筒状部21と、これらの筒状部21どうしを接続する複数の接続部22とを含む。筒状部21は、車幅方向に延びる複数の角稜25と、角稜25を介して互いに隣り合う複数の板部26とによって断面形状が多角形の筒状に形成される。複数の板部26のうち少なくとも一つにおける車幅方向外側の端部には、剛性が部分的に低くなる脆弱部27が形成されている。【選択図】 図2
