However, in the case of a vehicle body structure in which the floor panel is joined to the upper end of the side sill, such as the cabin floor of a truck, both ends of the cross member cannot be connected to the side sill, making it impossible to obtain sufficient strength in the width direction of the vehicle body. This problem arises.

前にてフロアパネル３上面に接合されている。 The cross member 4 has a square cross section, extends in the width direction of the vehicle body, and has an outer end 4 a cut off immediately before the side sill 2 . The inner end 4b of the cross member 4 is joined to the side surface of the tunnel portion 5 of the floor panel 3. That is, the outer end 4a of the cross member
is not joined to the side sill 2, but is joined to the upper surface of the floor panel 3 immediately in front of the side sill 2.
