摘要： The disclosure provides a vehicle body capable of suppressing the occurrence of cracks in a center pillar at the time of a side collision. A center pillar stiffener forms a hollow structure with a closed cross section by including a side wall which faces the outer surface of a pillar inner, a front wall which is formed by bending from a front end of the side wall to form a first ridge with the side wall and which is joined to the outer surface of the pillar inner, and a rear wall which is formed by bending from a rear end of the side wall to form a second ridge with the side wall and which is joined to the outer surface of the pillar inner. The pillar stiffener is provided with a bead recessed toward the pillar inner and orthogonal to the first and second ridges.

摘要： A vehicle body structure includes: a battery case that is disposed below a floor panel of a vehicle body and houses a battery; and a case-mounting frame that connects the battery case to a side sill provided on a side of the battery case in a vehicle width direction to support the battery case. The case-mounting frame includes a lower frame that straddles between the side sill and the battery case, and an upper frame that rises from the lower frame, supports the battery case, and is disposed side by side with the battery case in the vehicle width direction. The lower frame includes a fragile portion that is provided at a position located below the upper frame and is more fragile than another position other than the first position.
