Further, in this embodiment, a nut member 107 is previously fixed to the instrument panel member 106 in order to mount the bolt 102 for mounting the support bracket 99.

When a pipe member formed by hydroforming is used as the instrument panel member 106 in this manner, the instrument panel member can be formed with good formability, light weight, and rigidity, so that cowl rigidity and vehicle body rigidity can be improved. be able to.

In the embodiment shown in FIG. 20 as well, the other structures, functions and effects are almost the same as those of the previous embodiment shown in FIGS. 15 to 19. Therefore, in FIG. The same reference numerals are given to the parts, and detailed description thereof will be omitted.

In the correspondence between the configuration of the present invention and the above-described embodiment, the vehicle of the present invention corresponds to the open car of the embodiment, and the door opening corresponds to the door opening 6 and the cowl. The box corresponds to the cowl portion 33, but the present invention is not limited to the configuration of the above-described embodiment.

[0078]

According to the present invention, a front pillar is provided which is offset rearward from the left and right hinge pillars and extends upward to support the front window, and both front pillars are connected behind the instrument panel member. By providing the inter-pillar member extending in the vehicle width direction, there is an effect that the inter-pillar member provided in parallel with the instrument panel member can significantly improve the vehicle body rigidity.
