The reinforcement 221 is provided in 2 rows in the vehicle width direction, for example. Specifically, the 1 st stiffener 221a and the 2 nd stiffener 221b are provided as the stiffener 221. The 1 st stiffener 221a is a stiffener provided on the left side of the vehicle. The 2 nd stiffener 221b is a stiffener provided on the right side of the vehicle.
Since the reinforcement member 22 has 2 rows of reinforcements 221, i.e., the 1 st reinforcement 221a and the 2 nd reinforcement 221b, in the vehicle width direction of the vehicle, the vehicle body structure 2 can further improve the rigidity of the floor panel 21 in the vicinity of the mounting portion 211.
The 2 nd region 223 is a region that is provided between the rear end of the 1 st region 222 in the vehicle longitudinal direction and the rearmost rear end mounting portion of the plurality of mounting portions 211, and that decreases in distance from the rear end mounting portion in the vehicle width direction toward the rear of the vehicle. Specifically, in the case of the 1 st stiffener 221a provided on the left side of the vehicle, the rear end mounting portion is the 4 th left mounting portion 211d. In the case of the 2 nd reinforcement 221b provided on the right side of the vehicle, the rear end attachment portion is the 4 th right attachment portion 211h. An end portion of the 2 nd region 223 opposite to the side to which the rear end of the 1 st region 222 is joined is fixed to the joining portion 213.
The 1 st joining portion 224 joins the 1 st reinforcing member 221a and the 2 nd reinforcing member 221b at the joint position between the 1 st region 222 and the 2 nd region 223. The 1 st joint 224 is convex toward the lower side in the height direction of the vehicle, for example, and extends in the vehicle width direction of the vehicle. The 1 st joint 224 is fixed to the lower surface of the floor panel 21.
In the vehicle body structure 2, the 1 st stiffener 221a and the 2 nd stiffener 221b are joined by the 1 st joining portion 224 at the joint position between the 1 st region 222 and the 2 nd region 223 in this manner, whereby the bent portion of the stiffener 221 can be reinforced. Thus, the vehicle body structure 2 has the 1 st joint 224, and thus the rigidity of the floor panel 21 can be further improved.
In the above embodiment, the example in which the reinforcing member 22 has 2 rows of the reinforcements 221 in the vehicle width direction is shown, but the present invention is not limited thereto. The reinforcing member 22 may have 3 or more rows of reinforcements 221 in the vehicle width direction.
