Generally, when an impact load is applied to the vehicle from the front, the stress tends to be most concentrated in the curved portion 101 of the upper portion of the front pillar 100. In the front pillar 100, the curved portion 101 preferably has higher rigidity than other portions. On the other hand, in the above-mentioned conventional technique, the rear end 103c of the reinforcing member 103 is
The curved portion 101 is arranged further rearward. The cross-sectional shape of the front pillar 100 is significantly different between the front end and the rear end 103c of the reinforcing member 103. If the cross-sectional shape changes, the rigidity also changes significantly. As a result, the bending portion 10
The stress concentrates more on 1.

Therefore, in order to increase the rigidity of the curved portion 101, it is conceivable to extend the reinforcing material 103 to the rear of the curved portion 101. However, the reinforcement member 103 is simply replaced by the curved portion 10
There is a limit to increasing the rigidity only by extending the area to the rear of 1. To further increase the rigidity, it is conceivable to increase the plate thickness of the reinforcing material 103. However, increasing the plate thickness increases the vehicle body weight, which is not a good idea.

Means for Solving the Problems The present inventors have studied in detail the joint relationship between the front pillar and the roof side rail, and at the position of the curved portion of the front pillar, the front end portion of the roof side rail is utilized. The idea was to supplement the rigidity of the reinforcing material. That is, claim 1 is a vehicle body in which an upper end of a front pillar is curved and extends rearward, a roof side rail is extended rearward from a rear end of the curved portion, and the roof is supported by the roof side rail. The pillar is a vehicle body structure that is a closed cross-section consisting of an outside panel on the side of the vehicle body, a reinforcing material, and an inner side panel on the passenger compartment side, and extends the front end of the roof side rail into the closed cross-section body, In the position of the bend,
It is characterized in that it is passed through an intermediate portion between an inner side panel on the vehicle width center side and a reinforcing material on the outer side in the vehicle width direction and joined to the reinforcing material. Here, the "intermediate portion" refers to a position in the space between the inner side panel and the reinforcing member, which is separated from the inner side panel to the outer side in the vehicle width direction.

A front end portion of a roof side rail extending into a front pillar having a closed cross section is passed through an intermediate portion between an inner side panel and a reinforcing member at a position of a curved portion above the front pillar to form a reinforcing member. By joining, the rigidity of the reinforcing material can be supplemented by utilizing the front end portion of the roof side rail. As a result, it is possible to efficiently increase the rigidity of the curved portion of the upper portion of the front pillar where stress is concentrated. Moreover, since it is not necessary to increase the plate thickness of the reinforcing material, the weight of the vehicle body can be suppressed.

According to a second aspect of the present invention, the front end portion of the roof side rail is overlapped and joined to the inner side panel at a position rearward of the reinforcing member, and is inclined toward the intermediate portion as it extends toward the curved portion side. To do. As the front end of the roof side rail is inclined toward the middle part between the inner side panel and the reinforcement as it extends toward the curved side, and is joined to the reinforcement at the curved part, the front pillar and the roof side rail are In the joint portion of, the cross-sectional shape from the position of the curved portion to the position behind the reinforcing material can be gradually changed. As a result, rigidity can be ensured while suppressing changes in the cross section of the joint portion. Therefore,
It is possible to further suppress the stress concentration at the joint portion.

Next, the operation of the vehicle body structure having the above structure will be described with reference to FIGS. 3, 4 and 6. The present invention is
The roof side rail 50, which is thinner than the reinforcing member 30, reinforces the position of the curved portion 13 of the front pillar 12 to increase the rigidity. More specifically, the front end portion 51 of the roof side rail 50 extending into the front pillar 12 having a closed cross-section is provided with the inner side panel 40 at the position of the curved portion 13 above the front pillar 12.
It was passed through the intermediate portion 14 a between the reinforcing material 30 and the reinforcing material 30 and joined to the reinforcing material 30. The rigidity of the reinforcing material 30 can be supplemented by utilizing the front end portion 51. As a result, of the upper portion of the front pillar 12, it is possible to efficiently increase the rigidity of the bending portion 13 where stress is concentrated. Moreover, since it is not necessary to increase the plate thickness of the reinforcing material 30, the weight of the vehicle body can be suppressed.

Further, as shown in FIG. 4, the front end portion 51 is
Is inclined toward the intermediate portion 14a as it extends toward the bending portion 13 side, and at the position of the bending portion 13, the reinforcing material 30 is formed.
It was joined to the flanges 32 and 33 (see FIG. 6). At the joint between the front pillar 12 and the roof side rail 50, the cross-sectional shape from the position of the curved portion 13 to the position behind the reinforcing member 30 can be gradually changed. As a result, rigidity can be ensured while suppressing changes in the cross section of the joint portion. Therefore, it is possible to further suppress the stress concentration at the joint portion.
