Next, the operation of this embodiment will be described. In the side part structure of the vehicle body of the present embodiment, as shown in FIG. 2, when the barrier 50 contacts the side part of the vehicle body and a load (arrow A in FIG. 2) acts on the center pillar 10 from the side of the vehicle body, the gusset is set. Four
Although a load (indicated by an arrow B in FIG. 2) in the vehicle body inward direction acts on a joint portion between the floor cross member 30 and the floor cross member 30, the gusset 42 is coupled to the wheel house 34, and the wheel house 34 is attached to the vehicle body side. If the load is not applied from one side, the wheel house 34 does not move inward of the vehicle body. Therefore, the connecting portion between the gusset 42 and the wheel house 34, especially the connecting portion between the point P4 and the gusset 42 and the floor cross member 30, In particular, a tensile force (arrow C in FIG. 2) acts between point P6 and the load applied to the joint between gusset 42 and floor cross member 30, particularly point P6, can be relaxed.

Further, even if a load is applied to the wheel house 34 from the side of the vehicle body together with the center pillar 10, there is a tire inside the wheel house portion 40, and the load can be absorbed by this tire. The deformation toward the inside of the vehicle body is smaller than the deformation toward the inside of the vehicle body of the center pillar 10. Therefore, also in this case, the joint between the gusset 42 and the wheel house 34, in particular, the joint between the point P4 and the gusset 42 and the floor cross member 30, especially,
A tensile force (arrow C in FIG. 2) acts between point P6 and
It is possible to reduce the load applied to the joint between the gusset 42 and the floor cross member 30, particularly the point P6.

Next, the operation of this embodiment will be described. In the side part structure of the vehicle body of the present embodiment, the barrier abuts on the side part of the vehicle body,
When a load is applied to the center pillar 10 from the side of the vehicle body, a load in the vehicle body inward direction is applied to the connecting portion between the gusset 52 and the floor cross member 30, particularly point P6, but one end is connected to the point P6. The gusset 54 is connected to the wheel house 34,
If no load is applied to the side of the car body, the wheel house 3
Since 4 does not move inward of the vehicle body, a tensile force is applied between the connecting portion between the gusset 54 and the wheel house 34, particularly the point P4 and the connecting portion between the gusset 54 and the floor cross member 30, especially the point P6. Working, Gusset 5
It is possible to reduce the load applied to the connecting portion between the floor cross member 30 and the floor cross member 30, particularly to the point P6.

Further, even if a load acts on the wheel house 34 together with the center pillar 10 from the side of the vehicle body, there is a tire inside the wheel house portion 40, and the load can be absorbed by this tire. The deformation toward the inside of the vehicle body is smaller than the deformation toward the inside of the vehicle body of the center pillar 10. Therefore, also in this case, the load applied to the point P6 can be alleviated.
