Description of the Related Art Conventionally, a cowl panel partitions a vehicle compartment and an engine room in the front-rear direction of a vehicle, and is arranged in the width direction of the vehicle so as to support a lower edge of a front window of the vehicle. For example, as shown in FIGS. 6 and 8, in the cowl panel, the shape of the lower edge supporting portion of the front window is determined by the degree of the backward bending from the constraints such as the engine position and the cabin space, and the cross-sectional structure is also illustrated. 6 and a box-shaped closed cross-section type shown in FIG. Both ends of the cowl panel are connected to a front pillar and joined to a cowl side panel extending forward to prevent water from entering the vehicle interior.

It is joined to the side of the cowl side panel 4. Also, a reinforcement 50 that forms a closed section 51 with the rear surface of the cowl panel 10 is formed on the rear surface.
And both ends are joined to the side surface 91 of the front pillar 9.

On the other hand, in the case of the cowl panel 20, although the box-shaped closed section 23 can be made large,
The closed section 23 is greatly offset from the box-shaped closed section 92 of the front pillar 9 toward the front side of the vehicle, so that both closed sections 2
3,92 comrades are not directly connected, and it cannot be said that securing the body rigidity is effective. Even if braces are added to both ends of the rear surface of the inner panel 21 of the cowl panel 20 and connected to the side surface 91 of the front pillar 9, the two closed sections 2
Not directly connected to 3,92 and not very effective.

を提供することを目的とする。In the configuration of the cowl panel according to the present invention, the requirement for increasing the space on the vehicle compartment side is more severe than that of the cowl panel 10 or 20, and the position of the support portion at the lower edge of the front window is further closer to the engine side. In any of the configurations shown in the examples, in consideration of the problem that it is difficult to secure strong body rigidity, the body rigidity is improved by devising a configuration in which the closed section of the cowl panel is directly connected to the closed section of the front pillar. It is an object of the present invention to provide a cowl structure of a vehicle body that secures in a reliable manner and prevents intrusion of rainwater or the like from a cowl panel into a vehicle interior.
