DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.
This will be described in detail. FIGS. 1 and 2 show an engine according to the present invention.
1 shows a first embodiment of a side seal structure of a gin hood,
The same components as those of the conventional example are denoted by the same reference numerals.

That is, in this embodiment, the intake end 2a of the intake duct is provided in the vehicle-side space B surrounded by the hood ridge panel 3 and the fender panel 4 as in the case of the above-mentioned conventional example.
By opening the opening, the engine
From the vehicle side space B partitioned by the cartridge panel 3
Air is introduced into the lina 1. Also,
Mounting of the upper part of the fender panel 4 when the gin hood 5A is closed
It has a seal portion 7a which is elastically contacted with the flange 4a.
Hood side seal 7 on the hood inner panel 6
To the engine
To reduce noise outside the vehicle
I have to.

Here, in the first embodiment, the engine
The interior side 3 of the hood ridge panel 3 when the door 5A is closed
b of the side seal 7 with the seal lip 7b
It is formed integrally with the lower part of the screw 7a. Seal lip 7b
Is a hood lid in the natural state, as indicated by the broken line in FIG.
Open and close the engine hood 5A
Secure. However, the closing of the engine hood 5A ends.
The seal part 7a of the hood side seal 7 is in the upper part
Shown by solid line in contact with bead portion 4b of mounting flange 4a
As shown in FIG.
b moves toward the outside of the vehicle and its tip is indicated by a solid line
The hood ridge panel 3 comes into contact with the inside

You.

In the first embodiment, the tongue-like shape is used.
Although the seal lip 7b is provided ,
If the base is made hollow, its bending rigidity can be enhanced.
it can. In addition, seal hoods in the hood ridge panel 3
As shown in FIG. 1, the part corresponding to the
By bulging in the direction of
When the tip of the lip 7b is brought into contact
Is used to enhance the rigidity of the vehicle body and
Seal condition can be made more stable
You.

The engine hood having the above configuration
In the side seal structure, when no external force is applied, the hood
The seal lip 7b of the door side seal 7 is shown by a broken line in FIG.
As shown in the figure, the center of the body is more than the hood ridge panel 3.
Side without any obstacles.
The panel 5a can be opened and closed. When the engine hood 5A is completely closed, the fender panel 4
Due to the contact with the upper mounting flange 4a, the seal portion 7a is
The seal lip 7b is elastically deformed upward and
The panel 3 is brought into close contact with the inner side surface 3b of the vehicle. Therefore, Fender
Upper mounting flange 4a of panel 4 and hood ridge panel
3 and a gap X formed between the shoulder 3a and the engine
Engine A is isolated by the seal lip 7b,
The hot air in the room A flows into the vehicle side space B through the gap X
There is no. As a result, the low-temperature outside air
1 and the engine
The hot air of the air A passes through the gap X and the
It is not inhaled by the nut 1.

FIG . 3 is a side view of the engine hood according to the present invention.
2 shows a second embodiment of the seal structure, and shows the first embodiment shown in FIG.
The same components as in the example are denoted by the same reference numerals. This second
In the second embodiment, the engine is operated in the same manner as in the first embodiment.
In the closed state of the hood 5A, the hood ridge panel 3
The seal portion 7b abutting on the inside surface 3b of the vehicle
In addition to being integrally formed with the seal portion 7a of the seal 7,
Seal member 1 on the worship flange 3c at the top of the cartridge panel 3.
0, and a lip formed integrally with the seal member 10.
Elastically adheres the hook portion 10a to the corresponding surface of the fender panel 4.
It is characterized by having made it.

Therefore, in the case of the second embodiment,
Lip 10a of the sealing member 10 in addition to the id seal 7
Also closes the gap X and connects the engine room A and the vehicle side space B.
From the engine room A to the car side space B
The effect of preventing the inflow of hot air to the air becomes higher. Also deformed
When the fender panel 4 is replaced, the sealing member 10
The lip portion 10a comes into close contact with the new fender panel 4
In order to close the space X, it is necessary to replace the fender panel 4
No reduction in the hot air outflow prevention effect is observed.

[0015]

As is apparent from the above description, according to the present invention, the intake end of the intake duct is opened only by forming the seal lip integrally with the seal portion of the hood side seal.
Prevents inflow of hot air from the engine room into the car-side space
can do. According to the second aspect of the present invention,
For example, the seal provided on the worship flange of the hood ridge panel
Adhere the lip of the member to the corresponding surface of the fender panel
Thereby, the effect of preventing the inflow of the hot air can be further ensured.
