<p>A vehicle body stiffener structure is provided to enhance stiffness of a joint part between a side sill inner and a cross member, specifically to enhance lateral stiffness of a vehicle body against a side collision load. An extended planar portion 2h of the cross member 2 is joined to a bottom planar portion 1c of the side sill inner 1 so that the bottom planar portion 1c of the side sill inner 1 and the bottom planar portion 2b of the cross member 2 are flush with each other. A lateral portion 3b of a tie-down bracket 3 is joined to a bottom planar portion 2b of the cross member 2, while the lateral portion of the tie-down bracket 3 is a side planar portion 1b of the side sill inner 1. Accordingly, the tie-down bracket 3 serves to increase stiffness of the joint part between the side sill inner 1 and the cross member 2. Since the bottom planar portion 1c of the side sill inner 1 and the bottom planar portion 2b of the cross member 2 are flush with each other, lateral stiffness against a side collision load is increased. <IMAGE></p> |
