<p>PROBLEM TO BE SOLVED: To enable effective transmission of a load from a side sill by a cross member during a side collision.SOLUTION: A side sill 2 is joined to a floor panel 1 at an end part in a vehicle width direction, and a cross member 3 extending in the vehicle width direction is joined to an upper face of the floor panel 1. A connection flange part 20 extending from an end part in the vehicle width direction of the cross member 3 is joined to an upper face 11a of the side sill 2 (a side sill inner 11). An inclination part 22 which is positioned gradually downward toward the outer side in the vehicle width direction and reaches the upper face 11a of the side sill inner 11, is formed at a base end part of the connection flange part 20. A bead part 21 extending toward the outer side in the vehicle width direction so as to include the vehicle width direction position corresponding to the base end part of the inclination part 22 is formed in the connection flange part 20. Force F input from an obliquely lower side with respect to the side sill 2 during a side collision is transmitted to the cross member 3 via the inclination part 22 effectively.</p> |
