PROBLEM TO BE SOLVED: To provide a vehicular side part body structure capable of improving the transmission performance of a load upon a collision of a vehicle, even if a comparatively large space portion is generated between a lower corner on a vehicle outside in a side sill and a joint member.SOLUTION: A bulkhead 10 disposed in a closed cross-section space C of a side sill 5, is disposed separately from an outer lower corner portion in a side sill outer lane 52. The bulkhead 10 is composed of a first member 20 which has a front partitioning wall 21, a rear partitioning wall 22, and a coupling surface 23 coupling the front partitioning wall 21 and the rear partitioning wall 22 on the outer side in a vehicle width direction; and a second member 30 composed of a lower surface portion 35 disposed between an outer lower portion in the vehicle width direction W at the first member 20 and an outer lower corner portion of the side sill outer lane 52, and opposing to the lower corner portion of the side sill outer lane 52, and a pair of fore-and-aft side part extending portions 33 formed so as to extend in parallel with an obliquely inward and upward direction X, and joined to the front partitioning wall 21 and the rear partitioning wall 22 by the side part extending portion 33.

    【課題】サイドシルにおける車外側の下角と節部材との間に比較的大きな空間部が生じた場合であっても、車両の側突時の荷重の伝達性能を向上できる車両の側部車体構造を提供することを目的とする。【解決手段】サイドシル5の閉断面空間Cに配置されたバルクヘッド10は、サイドシルアウタレイン52における外下角部と離間して配置されるとともに、前方隔壁21及び後方隔壁22と、車幅方向外側で前方隔壁21と後方隔壁22とを連結する連結面23とを有する第1部材20と、第1部材20における車幅方向Wの外側下部と、サイドシルアウタレイン52の外下角部との間に配置され、サイドシルアウタレイン52の下角部に対向する対向下面部35と、内斜め上方向Xに平行に延びるように形成された前後一対の側方延設部33とで構成されるとともに、側方延設部33によって第1部材20の前方隔壁21及び後方隔壁22に接合された第2部材30とで構成されている。【選択図】図2
