PROBLEM TO BE SOLVED: To efficiently transmit collision load input to a front side frame to a side sill and absorb it while reducing weight of a vehicle body. SOLUTION: A part F2 of the collision load F1 input to the front side frame 12 is transmitted to the side sill 14 through an outrigger 15, and the other part F3 is transmitted to a tunnel frame 17 through an extension 18. At this time, since a rear end of the front side frame 12 and a front end of the side sill 14 are offset in a left/right direction, bending moment M making the front end of the side sill 14 as fulcrum is applied to the outrigger 15. However, since a front end of a floor frame 20 is connected to a rear edge of the outrigger 15 at a right angle and a rear end of the floor frame 20 is connected to a cross member 19, the rigidity of the outrigger 15 is sufficiently enhanced by the thin floor frame 20 of light weight, and the collision load F1 is efficiently transmitted to the side sill 14.
