PROBLEM TO BE SOLVED: To provide a vehicular side part body structure capable of improving vibration attenuating performance or NVH performance, and the transmission performance of a load upon a collision of a vehicle.SOLUTION: A bulkhead 10 for partitioning a closed cross-section space C of a side sill 5 in a vehicle fore-and-aft direction has a front partitioning wall 21 and a rear partitioning wall 22 for partitioning the closed cross-section space C in the vehicle fore-and-aft direction, a side part vertical coupling surface 23a for coupling the front partitioning wall 21 and the rear partitioning wall 22 on the outer side in a vehicle width direction, a flange 26a accepting the joining with an upper surface 511 of a side sill inner 51, and a flange 26b for accepting the joining with a vertical wall 512 of the side sill inner 51. The bulkhead 10 is joined with the side sill inner 51 by the flanges 26a and 26b, and a vibration attenuating member 40 is arranged between the side part vertical coupling surface 23a and the vertical wall 522 of the side sill outer REIN 52, and an upper coupling surface 23b is formed to be a generally linear in a direction parallel with an obliquely inward and upward direction X, in a vehicle front view.
【課題】振動減衰性能、あるいはNVH性能を向上するとともに、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を車両前後方向に仕切るバルクヘッド10は、閉断面空間Cを車両前後方向に仕切る前方隔壁21および後方隔壁22と、車幅方向外側で前方隔壁21と後方隔壁22とを連結する側方縦連結面23aと、サイドシルインナ51の上面511との接合を許容するフランジ26aと、サイドシルインナ51の縦壁512との接合を許容するフランジ26bとを有し、フランジ26a,26bによりサイドシルインナ51に接合され、側方縦連結面23aとサイドシルアウタレイン52の縦壁522との間に振動減衰部材40が配設されるとともに、車両正面視において、上部連結面23bが内斜め上方向Xに平行な方向の略直線状となるよう形成された。【選択図】図1
