付けられる場合がある。A radiator core upper 6 and a first cross member 7 are vertically arranged behind the bumper 2, and they are vertically connected by a hood lock stay 5. An under cover 8 is attached to the lower surface of the first cross member 7. A condenser (heat dissipation device) 9 of an air conditioner is arranged between the radiator core upper 6 and the first cross member 7.
A radiator (heat dissipation device) 10 is arranged behind it. Reference numeral 11 denotes an intercooler (heat dissipation device), which may be attached depending on the vehicle model.

ら行われる。Reference numeral 12 is an intake duct for introducing outside air A into an air cleaner (not shown). The outside air introduction port 13 of the intake duct 12 is located between the radiator core upper 6 and the engine hood 1, the upper end 13a thereof abuts the lower surface of the engine hood 1 through the seal member 14, and the lower end 13b thereof is the radiator core upper 6. However, since the tip of the engine hood 1 is close to the lower end 13b of the outside air introduction port 13, the introduction of the outside air A from the front grill 3 is substantially the same as the outside air introduction. It is performed from a gap portion d between the lower end 13b of the mouth 13 and the engine hood 1.

５を設けたために、フロントグリル３から入った水Ｗ2
の一部は下に落ちず、そのまま遮水板１５の上面に沿っ
た状態で外気導入口１３内へ侵入するおそれがある。However, in such a conventional technique, the water W 1 that has entered through the lower opening 4 is formed by the formation of the water shield plate 15 as described above. Although it is possible to prevent the water W 2 from entering the upper side of the front grille 3, the water W 2 that has entered from the upper front grille 3 does not flow into the water blocking plate 15.
Due to the formation of the above, it becomes easier to enter the outside air introduction port 13. That is, when the road is badly flooded and the running speed of the vehicle plunging into the road is high, the water W 2 also enters from the front grille 3 on the upper side.
Water W 2 entered from the front grill 3 due to the provision of No. 5
There is a possibility that a part of the water will not fall downward and will enter the outside air introduction port 13 along the upper surface of the water shield plate 15 as it is.

への適用は不向きである。The formation of the water shield plate 15 is also disadvantageous in terms of the performance of introducing the outside air A from the front grill 3. In other words, of the outside air A entering from the front grill 3,
A state in which only the amount of water that has entered between the tip of the water shield plate 15 and the engine hood 1 is guided into the intake duct 12, and the amount of outside air A introduced into the intake duct 12 due to the presence of the water shield plate 15 is limited. It has become. Therefore, such an intake structure is not suitable for application to a high-power engine that needs to introduce a large amount of outside air A.

エンジンへの適用も可能である。According to the first aspect of the present invention, the water blocking plate, which substantially shields the front-rear distance between the bumper and the heat dissipation device, is provided above the opening of the bumper over at least the range of the outside air introduction port in the vehicle width direction. Since it is provided, the water entering from the lower opening is blocked by this water blocking plate and does not enter the intake duct. Further, the water that has entered from the upper front grill does not enter the intake duct because it falls on the water shield plate and is discharged as it is. Furthermore, since this water shield plate is attached to the bumper and is not located in the vicinity of the outside air introduction port of the intake duct unlike the conventional case, the amount of outside air introduced is not limited by this water shield plate. It can also be applied to high-power engines.

ない。Further, since the sloped portion is lifted up by being pushed by the water entering from the opening of the bumper, the gap between the sloped portion and the heat radiating portion is closed and the water impermeability is further improved. . In addition, since the inclined portion only momentarily lifts to the upper side and immediately returns to the original inclined state, the drainage promoting action of water due to the formation of the above-mentioned gap is not substantially affected.

ている。Reference numeral 21 is the water shield plate of this embodiment. The water shield plate 21 is formed over a substantially entire vehicle width direction range D of the opening 4 formed in the bumper 2 (see FIG. 2), and its front end is attached to the upper end of the bumper 2 by a clip 22 and its rear end. Reference numeral 21a has an uneven shape corresponding to the member located at the rear. This water blocking plate 21 is a bumper 2
It is important that the bumper 2 is attached to a portion above the opening 4 and must not be attached to a portion below the opening 4 of the bumper 2. This water shield plate 21 basically shields the front-rear space between the bumper 2 and the heat dissipation device (the condenser 9, the auxiliary fan 16, etc.), but in front of the condenser 9, the hood lock stay 5 and tanks. Since 17 is also located,
The rear end 21a has an uneven shape in order to avoid these. Further, the rear side portion from the broken line L of the water shield plate 21 is a downward inclined portion 23 (see FIGS. 3 and 4), and the rear end 21a of the inclined portion 23 and the heat dissipation device 9 located on the rear side thereof. , 16 is provided with a slight gap S.

れる。Next, the function of the water shield plate 21 will be described mainly with reference to FIG. When a vehicle runs through a flooded road at a considerable speed, not only the water W 1 entering from the opening 4 of the bumper 2 but also the water W 2 from the upper front grille 3
Comes in. Front grille 3 has opening 4
Since the position is higher than this, the water W 2 entering from the front grill 3 is not as strong as the water W 1 entering from the lower opening 4. Therefore, the water W 2 from the front grill 3 falls into the lower water-blocking plate 21 after entering the inside, and is directly discharged downward. At this time, the rear side portion of the water shield plate 21 is the downwardly inclined portion 23, and the gap S is formed between the rear end 21a and the heat dissipation devices 9 and 16. The downward discharge of water W 2 is promoted.

水Ｗ1 の遮水性は更に万全なものとなる。On the other hand, the water W 1 that has entered through the opening 4 is stronger than the water W 2 from the front grill 3.
Therefore, the water W 1 from the opening 4 hits the heat dissipation devices 9 and 16 due to the momentum thereof and becomes an upward flow, and tries to reach the upper outside air introduction port 13, but the flow of the water W 1 of the water shield plate 21. This water W 1 does not reach the upper outside air inlet 13 because it is blocked by the presence. Particularly, since the upward water W 1 hits the inclined portion 23 of the water shield plate 21 from the lower side and lifts the inclined portion 23 so as to rotate upward (state of the inclined portion 23 ′ in FIG. 4), the inclination The rear end 21a 'of the portion 23' comes into contact with the heat dissipation devices 9 and 16, and the gap S
Will be blocked. Therefore, the water impermeability of the water W 1 by the water impermeable plate 21 is further enhanced.

消し合うようなことはない。It should be noted that since the inclined portion 23 only momentarily lifts to the upper side and immediately returns to the original inclined state, the drainage promoting action of the inclined portion 23 on the water W 2 entering from the front grill 3 is substantially caused. It will not be hindered. In addition, the water W 1 entering from the lower opening 4 and the water W 2 entering from the upper front grill 3 have a slightly later timing of entering the inside, so the water W 2 due to the existence of the gap S. The drainage promoting action of 1 and the water impermeability of the water W 1 by closing the gap S do not mutually cancel each other's actions.

ない。Further, the rear side portion of the water shield plate 21 has an inclined portion 23.
That is, it is advantageous even in the event of a light collision of a car. For example, when the bumper 2 of the automobile collides lightly with an obstacle, the heat dissipating devices 9 and 16 cause the bumper 2 to
With respect to the heat dissipation devices 9 and 16, the heat dissipation devices 9 and 16 come into contact with the rear end 21a of the water shield plate 21, but the inclined portion 23 is formed so that the inclined portion 23 is separated from the polygonal line L. Bend in the direction that further increases the inclination (the inclined portion 2 in FIG.
3 ″). That is, since the water shield plate 21 is not stretched between the bumper 2 and the heat dissipation devices 9 and 16, the water shield plate 21 does not damage the heat dissipation devices 9 and 16.

Since it was formed over the entire vehicle width direction range D of the portion 4,
Water W from Part 41Goes beyond the upper side of the heat dissipation devices 9 and 16
It is possible to prevent the entry into the engine room E. That is,
Water W entering through the opening 4 1Is an upward flow with that momentum
As it is, it goes beyond the upper side of the heat dissipation devices 9 and 16 as it is.
The water shield plate 19
Is provided over the entire vehicle width direction range D of the opening 4.
Than this water W1Invasion of engine room E
I tried to prevent it. The engine 18 itself is water W1Is somewhat
It has a structure that will not cause any problems, but the engine 18
Frequent exposure to water was not always desirable
It has a structure like this. Water W1Outside air inlet 13
If you just want to prevent it from entering the inside,
It is not necessary to provide the opening 4 over the entire vehicle width direction range D.
The width of the vehicle that is at least under the outside air inlet 13
It may be formed only in the facing area.
