a floor panel that extends from the center tunnel to both sides of the vehicle in a right-left direction; a floor cross member that is provided on an upper face of the floor panel and that extends in the right-left direction of the vehicle, straddling the center tunnel; a reinforcing member joined to an upper face of the center tunnel and to a front face of the floor cross member; a forward tunnel reinforcement that extends in the front-rear direction of the vehicle and that is provided on a lower face of the center tunnel; a rearward tunnel reinforcement that extends in the front-rear direction of the vehicle and that is provided on the lower face of the center tunnel, the rearward tunnel reinforcement located rearward from the forward tunnel reinforcement; and an overlap portion in which the forward tunnel reinforcement and the rearward tunnel reinforcement overlap each other, the overlap portion provided downward from the floor cross member. ### Claim 2 (depends on 1) The body according to claim 1, wherein the reinforcing member is a plate-shaped member that is joined to the upper face of the center tunnel on a first side of the reinforcing member and is joined to the front face of the floor cross member on a second side of the reinforcing member. ### Claim 3 (depends on 1) The body according to claim 1, wherein, of the upper face of the center tunnel, at least a range located above the floor cross member is an inclined face that inclines downward from forward to rearward, and wherein the reinforcing member is joined to the inclined face of the center tunnel. ### Claim 4 (depends on 1) The body according to claim 1, wherein a front end of the reinforcing member faces the overlap portion on either side of the center tunnel. ### Claim 5 The body according to 1, wherein a rigidity of the forward tunnel reinforcement is higher than a rigidity of the rearward tunnel reinforcement. ### Claim 6 (depends on 5) The body according to claim 5, wherein a yield strength of a material making up the forward tunnel reinforcement is higher than a yield strength of a material making up the rearward tunnel reinforcement. ### Claim 7 The body according to 1, wherein a yield strength of a material making up the forward tunnel reinforcement is higher than a yield strength of a material making up the center tunnel.
