Exhaust from Thereby, drainage property can be improved.

<Side cover>
As shown in FIG. 1, the side cover 3 is disposed at the side edge 2 a in the longitudinal direction of the cowl top 2. The side cover 3 includes a cover main body 31 joined to the side edge 2 a and a hook-shaped part 32 projecting from the cover main body 31. The cover main body 31 is a member that covers the side edge 2 a of the cowl top 2.

  As shown in FIG. 2 (b), the cover main body 31 includes a first bent portion 31a and a second bent portion 31b, a lower side wall 31c forming the ridged portion 32 to the first bent portion 31a, and 1) an upper wall 31d forming the first bent portion 31a to the second bent portion 31b; an upper side wall 31e positioned above the second bent portion 31b; and a lower surface joint 31f joined to the lower surface of the cowl top 2; And.

The bowl-shaped portion 32 includes a drainage receiving portion 32a, a drainage guiding portion 32b, and a guide portion 32c. The wedge-shaped portion 32 is provided 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 distal end joint portion 32d formed at the distal end of the guide portion 32c and a concave portion 32e (see FIG. 3B) formed at the downstream side of the distal end joint portion 32d. .

The drainage guiding portion 32b extends downward from the drainage receiving portion 32a, as shown in FIG.
The guide portion 32 c is formed so as to extend from the cover main body portion 31 so as to bend, and has a shape that protrudes toward the upper side of the vehicle outer side. As shown in FIG. 3 (b), the distal end bonding portion 32 d is in contact with the outer surface of the seal attachment portion 23 of the cowl top 2. The concave portion 32e is shaped to bulge outward 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 includes the weir-shaped portion 32, and after receiving the staying water Q collected from the drainage port 4 by the drainage receiving portion 32a, the drainage guiding portion The stagnant water Q can be discharged by induction to a predetermined discharge location by 32b.

  A distal end joint portion 32d is formed in the drainage receiving portion 32a, and as shown in FIG. 3B, the distal end joint portion 32d is in contact with the outer surface of the seal attaching portion 23. For this reason, the drainage receiving portion 32 a can be formed into a closed cross-sectional shape by the distal end joint portion 32 d, the cowl top 2, and the cover main body portion 31.

  Thereby, even if a large amount of staying water Q flows into the drainage receiving portion 32a from the drainage port 4, the staying water Q which has flowed in is reliably collected without inadvertently diffusing into the engine room EG. It can flow to the lower drainage guiding part 32b.

  Further, the drainage receiving portion 32a is provided with the recessed portion 32e, so that the staying water Q flowing into the recessed portion 32e is retained even when a large amount of staying water Q flows in from the drain port 4 The flow can be buffered and reliably flowed to the lower drainage guiding portion 32b.

  As shown in FIG. 5, the pinching angle θ (θ1, θ2, θ3) that the guide portion 32c makes with the cover main body portion 31 is the pinching angle θ1 on the upstream side of the concave portion 32e in the drainage receiving portion 32a (FIG. 4). The sandwiching angle θ2 (see FIG. 4 (b)) and θ3 (see FIG. 4 (c)) of the drainage guiding portion 32b are larger (θ1 <θ2, θ3) than (a). The upstream sandwiching angle θ1 is an acute angle. In the drainage guiding portion 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 a large amount from the drainage port 4 (see FIG. 4A) by making the pinching angle θ smaller on the upstream side of the concave portion 32e than the drainage guiding portion 32b. The stagnant water Q (see FIG. 6) can be smoothly flowed to the downstream concave portion 32e. Since the drainage guiding portion 32b is smaller than the upstream side of the concave portion 32e, the drainage guiding portion 32b can secure the flow path of the staying water Q collected reliably. In the drainage guiding portion 32b, the stagnant water Q can be reliably guided to the downstream side without being inadvertently dissipated to the outside because the sandwiching angle θ3 on the downstream side is larger than the sandwiching angle θ2 on the upstream side .

  As shown in FIG. 6, in the drainage structure 1 of the vehicle according to the embodiment of the present invention, a waterproof cover 5 which is a waterproof member is disposed below the lower end portion 32f of the drainage guiding portion 32b. The lower end 32f of the drainage guiding portion 32b is located at the rear end of the drainage guiding portion 32b. The waterproof cover 5 is a member which covers the upper part of the built-in apparatus which is not shown in figure, 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 upper portion of the waterproof cover 5.

The effects of the drainage structure 1 for a vehicle according to the embodiment of the present invention configured as described above will be described mainly with reference to FIGS. 5 and 6.
The drainage structure 1 of the vehicle has the drainage port 4 provided on the upper surface of the cowl top 2 so that the staying water Q is promptly recovered and drained from the drainage port 4.

The drainage structure 1 of the vehicle is provided with the weir-shaped portion 32 so that the staying water Q collected from the drainage port 4 is received by the drainage receiving portion 32a and then dropped from the lower end 32f of the drainage guiding portion 32b.
Since the waterproof cover 5 is disposed below the lower end 32f of the drainage guiding portion 32b, the waterproof cover 5 receives stagnant water Q dropped from the lower end 32f of the drainage guiding portion 32b. The stagnant water Q received by the waterproof cover 5 is discharged along the waterproof cover 5 to the lower side of the vehicle.

  Thus, after the drainage structure 1 of the vehicle is received by the waterproof cover 5, it is led to the lower side of the vehicle which is the drainage path of the staying water Q set in advance and discharged. 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 is possible to deform | transform suitably and to implement. For example, in the present embodiment, the collected staying water Q is received by the waterproof cover 5 and then discharged to the lower side of the vehicle. However, the present invention is not limited thereto. You may discharge it directly downward without receiving it.
