It is equipped with.

The bowl-shaped part 32 includes a drain receiving part 32a, a drain guiding part 32b, and a guide part 32c. The hook-shaped portion 32 is provided so as to protrude from the cover main body portion 31 to the vehicle outer side.
The drainage receiving portion 32a is located below the drainage port 4 (see FIG. 1). The drainage receiving portion 32a is formed with a tip joint portion 32d formed at the tip of the guide portion 32c and a concave portion 32e (see FIG. 3B) formed on the downstream side of the tip joint portion 32d. .

As shown in FIG. 1, the drainage guiding part 32b extends downward from the drainage receiving part 32a.
The guide portion 32c is formed so as to bend from the cover main body portion 31, and has a shape protruding toward the upper outside of the vehicle. As shown in FIG. 3B, the tip joint portion 32 d is in contact with the outer surface of the seal mounting portion 23 of the cowl top 2. The concave shaped portion 32e has a shape that bulges to the outside of the vehicle, specifically, forward, downward, and rearward of the vehicle.

  With this configuration, as shown in FIG. 6, the drainage structure 1 of the vehicle is provided with the bowl-shaped portion 32, so that the accumulated water Q collected from the drainage port 4 is received by the drainage receiving portion 32 a and then the drainage guiding portion. The stagnant water Q can be discharged by being guided to a predetermined discharge location by 32b.

  A tip joint portion 32d is formed in the drainage receiving portion 32a, and the tip joint portion 32d is in contact with the outer surface of the seal mounting portion 23 as shown in FIG. For this reason, the drainage receiving portion 32a can be formed in a closed cross-sectional shape by the tip joint portion 32d, the cowl top 2, and the cover main body portion 31.

  As a result, even if a large amount of accumulated water Q flows into the drain receiving part 32a from the drain port 4, the accumulated accumulated water Q is surely collected without being inadvertently diffused into the engine room EG. It can flow to the lower drainage guiding portion 32b.

  Further, since the drainage receiving portion 32a includes the concave shaped portion 32e, even when a large amount of the accumulated water Q flows from the drain port 4, the retained water Q flowing into the concave shaped portion 32e is retained. The flow can be buffered and reliably flowed to the lower drainage guiding portion 32b.

  As shown in FIG. 5, the sandwiching angle θ (θ1, θ2, θ3) formed by the guide portion 32c with respect to the cover main body 31 is the sandwiching angle θ1 on the upstream side of the recessed portion 32e in the drainage receiving portion 32a (FIG. 4). The sandwich angle θ2 (see FIG. 4 (b)) and θ3 (see FIG. 4 (c)) of the drainage guiding portion 32b are larger (θ1 <θ2, θ3) than (see (a)). The upstream sandwiching angle θ1 is an acute angle. In the drainage guiding part 32b, the sandwiching angle θ3 on the downstream side is larger than the sandwiching angle θ2 on the upstream side (θ2 <θ3).

  With this configuration, the drainage structure 1 of the vehicle flows in a large amount from the drainage port 4 (see FIG. 4A) by setting the sandwiching angle θ to be smaller on the upstream side of the concave shaped portion 32e than the drainage guiding portion 32b. The staying water Q (see FIG. 6) can be smoothly flowed to the downstream concave portion 32e. Since the drainage guiding part 32b is smaller than the upstream side of the concave shaped part 32e, the drainage guiding part 32b can secure a flow path of the collected water Q that is reliably collected. In the drainage guiding part 32b, the downstream sandwiching angle θ3 is larger than the upstream sandwiching angle θ2, so that the staying water Q can be reliably guided downstream without being inadvertently diffused to the outside. .

The lower end part 32f of the drainage guidance part 32b is located at the rear end part of the drainage guidance part 32b. The waterproof cover 5 is a member that covers the upper part of a built-in device (not shown) and has sufficient waterproof performance. The staying water Q discharged from the lower end portion 32 f of the drainage guiding portion 32 b falls on the top of the waterproof cover 5.

Operations and effects of the vehicle drainage structure 1 according to the embodiment of the present invention configured as described above will be described mainly with reference to FIGS. 5 and 6.
Since the drainage structure 1 of the vehicle is provided with the drainage port 4 on the upper surface of the cowl top 2, the accumulated water Q is quickly collected and discharged from the drainage port 4.

Since the drainage structure 1 of the vehicle is provided with the bowl-shaped portion 32, the accumulated water Q collected from the drainage port 4 is received by the drainage receiving portion 32a and then dropped from the lower end portion 32f of the drainage guiding portion 32b.
Since the waterproof cover 5 is disposed below the lower end portion 32f of the drainage guiding portion 32b, the staying water Q dropped from the lower end portion 32f of the drainage guiding portion 32b is received by the waterproof cover 5. The staying water Q received by the waterproof cover 5 is transferred to the lower side of the vehicle through the waterproof cover 5.

  In this way, the drainage structure 1 of the vehicle is guided by the waterproof cover 5 and then discharged under the vehicle, which is a preset drainage path for the accumulated water Q. Thereby, sufficient drainage performance as a vehicle can be obtained.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change and implement suitably. For example, in the present embodiment, the collected accumulated water Q is received by the waterproof cover 5 and then discharged downward of the vehicle. However, the present invention is not limited to this. It may be discharged directly downward without receiving.
