The vehicle 10 to which the vehicle front structure according to the present embodiment is applied is basically configured as described above. Next, the function and effect will be described.

In the present embodiment, the center side in the vehicle width direction of the cowl top 26 is supported from below by the glass support member 24 that extends from the front end of the windshield support panel 18 toward the front of the vehicle. Since the side is supported by the left and right damper base supports 72a and 72b from below, the dashboard upper that supports the cowl top 26 from below can be omitted. Therefore, it is possible to bring the engine closer to the passenger compartment as compared with the prior art, so that the dashboard upper can be omitted, and the vehicle body can be reduced in size. Further, since the clearance between the cowl top 26 and the engine can be increased by the amount that the dashboard upper can be omitted, the cowl top 26 can be lowered as compared with the prior art, and the field of view ahead of the vehicle can be improved.

Further, in the present embodiment, since the front end flange 58 of the drainage groove 54 supports the partition wall 60 of the cowl top 26 from below, the support rigidity of the cowl top 26 can be improved.

Further, in the present embodiment, since the vehicle inner side edge portions 84 of the left and right damper base supports 72a and 72b support the vehicle inner side wall 86 of the cowl top 26 from below, the support rigidity of the cowl top 26 can be improved. .

Further, in the present embodiment, the glass support member 24 is provided with a drainage groove 54 at a portion extending forward from the coupling portion 56 with the windshield support panel 18 (see FIG. 5). Therefore, when the water flows down from the windshield glass 16, the water flowing down from the windshield glass 16 can be drained left and right by the drain grooves 54. For this reason, it can avoid suitably that the water which flowed down flows into an engine room.

Further, in this embodiment, the partition wall 60 of the cowl top 26 can contact the front end flange 58 of the drainage groove 54 via the seal member 70 to close the space including the drainage groove 54 (see FIG. 5). ), A relatively large amount of water can be drained. In other words, by providing the partition wall 60 of the cowl top 26 positioned above the drainage groove 54 at the tip of the drainage groove 54, the volume of the space portion including the drainage groove 54 is increased correspondingly, and a relatively large amount is obtained. Water can be drained.

In the present embodiment, both ends of the drainage groove 54 in the vehicle width direction are connected to the upper surfaces of the left and right damper base supports 72a and 72b, and the damper base supports 72a and 72b extend between the cross member 14 in the vehicle width direction. In order to form the drainage channel D1, the first drainage channel D1 can be used to drain water to the outside. FIG. 8 is a perspective view of the glass support member 24 and the left and right damper base supports 72a and 72b as viewed from the bottom surface side, and the water introduced into the drainage groove 54 faces the upper surface side of the left and right damper base supports 72a and 72b. The state of being drained is shown by a broken line.

That is, the water introduced into the drainage groove 54 of the glass support member 24 circulates on the upper surfaces of the left and right damper base supports 72a and 72b disposed on the left and right end portions of the vehicle 10 (see the arrows in FIG. 9). The water is drained from the drainage channel D1 to the first drainage port 78 of the upper member inner panel 76, or is drained from the second drainage channel D2 to the second drainage port 79 of the upper member inner panel 76.

In the present embodiment, as shown in FIG. 13, the glass support member 24 is moved from the front end (front end flange 30 a) of the windshield support panel 18 to the lower part of the windshield glass 16 at the central portion 39 of the windshield support panel 18.

In FIG. 13, an external force input from a direction orthogonal to the axis of the glass support member 24 is F1, and an external force input from a direction inclined horizontally from the external force F1 is F2. Although the external force input toward the direction is illustrated as F3, the input angles of these external forces F applied to the outer surface of the windshield glass 16 are not limited to the angles of the external forces F1 to F3. Absent.

In other words, in the present embodiment, it is possible to suitably avoid the generation of reaction forces that oppose each other and cancel each other, so that the external force F is input at an arbitrary angle with respect to the outer surface of the windshield glass 16. Even in such a case, the impact load due to the external force F can be suitably absorbed.

As mentioned above, although 1st Embodiment of this invention was described in detail with reference to drawings, this invention is not limited to this, In the range which does not deviate from the main point of invention, it can change suitably.
