DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing structure for a space in a fender which prevents hot air from flowing into the space in the fender.

[0002]

2. Description of the Related Art As shown in FIG. 4, an air cleaner (not shown) is installed in an engine room surrounded by an engine hood 1 and an apron 4, and an air inlet 6 of an intake duct of the air cleaner is connected to the apron 4 and a fender panel. Vehicles arranged in a vehicle-side space 8 surrounded by 2 are well known. This is intended to reduce the intake air temperature by taking in outside air having a lower temperature than a portion partitioned from the hot air in the engine room 12, and to increase the efficiency of the engine by introducing high-density air.

However, the upper mounting flange 2a of the fender panel 2 and the shoulder 4a of the apron 4 as a vehicle body structure.
Between the upper mounting flange 2a and the shoulder 4a.
A gap G is inevitably formed in a portion other than the portion fixed by bolts to the engine room 1.
The hot air E in 2 circulates into the vehicle side space 8, and the air intake 6 of the air intake duct of the air cleaner sucks the hot air E,
There was a problem that the intake air temperature did not drop so much.

In order to solve the above problem, FIG.
As shown in the figure, a seal lip 11 is provided on the inner surface of the engine hood 1 to close the gap G between the upper mounting flange 2a and the shoulder 4a, and to prevent the hot air E in the engine room 12 from flowing into the vehicle side space 8. I try to prevent it.

[0005]

In the above structure, the seal lip 11 can prevent the hot air E in the engine room 12 from flowing into the vehicle side space 8 through the gap G, but the engine hood 1 is closed. In order to make the seal lip 11 abut on the shoulder 4a of the apron 4 in the closed state, the seal lip 11 is attached to the shoulder 4a of the normal apron 4 shown in FIG.
However, as shown in FIG. 5, the length of the shoulder 4a is extended in the direction inside the engine room 12 by the width B so that the seal lip 11 abuts. for that reason,
There is a problem that the inside of the engine room 12 is narrowed by the extended B width and the cost is increased.

When the engine hood 1 is closed, the gap G is closed by the seal lip 11, but when the engine hood 1 is opened in an idling state of the engine, the seal lip 11 is disengaged from the shoulder 4a of the apron 4. The gap G opens apart. At this time, most of the hot air E in the engine room 12 is discharged upward, but a part of the hot air flows into the vehicle side space 8 from the gap G, which is not preferable for the engine in an idling state.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sealing structure for a space in a fender space in which a sealing member always prevents hot air from flowing into a vehicle side space, thereby reducing costs and avoiding obstacles during work.

In this case, an upper mounting flag of the fender panel 2 is provided.
A bead portion 3 having a convex curved surface is provided at the end of the
A concave curved surface 7a engaging with the convex curved surface of No. 3 is formed at the tip,
The engine room 12 and the vehicle side space 8 communicate with each other.

This is characterized in that the inflow of hot air into the room 12 is prevented .

[0009]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is an engine hood, 2 is a fender panel, and 4 is an apron. The air intake 6 of the air intake duct of the air cleaner (not shown) installed in the engine room 12 surrounded by the engine hood 1 and the apron 4 has the apron 4 and the fender panel 2.
It is arranged in the vehicle side space 8 surrounded by. Reference numeral 5 denotes a side member fixed to the apron 4 on the side of the vehicle-side space 8.

Further, the gap G which communicates the engine 12 and the vehicle-side space 8 between the shoulders 4a of the upper mounting flange 2a of the fender panel 2 apron 4 is inevitably formed. As shown in FIG. 3, there is no gap G at a fixed interval where the upper mounting flange 2a is fixedly fastened to the shoulder 4a with the bolt 13;
Others have a gap G as shown in FIG.

The invention in the above configuration, bi edge in the convex surface of the upper mounting flange 2a of the fender panel 2
A seal member 7 that is provided with a bead portion 3 , has a concave curved surface 7 a that engages with a convex curved surface of the bead portion 3 at its tip, and communicates the engine room 12 with the vehicle-side space 8 to close a gap G. Is fixed to the upright surface of the apron 4 on the engine room 12 side with a stopper 10 such as a clip.

Further , a concave step 9 is formed on the upright surface of the apron 4, and the seal member 7 is fixed to the concave step 9.

Since the present invention has the structure as described above, the sealing member 7 has the concave curved surface 7a at the tip thereof unevenly engaged with the convex curved bead portion 3 at the edge of the upper mounting flange 2a to form the gap G. It is always closed.

[0014] Therefore, a reliable gap G without departing from the edge of the upper mounting flange 2a sealing member 7 which irregularities engaged with the bead portion 3 of the convex curved edges by vibration of the upper mounting flange 2a It is closed to prevent the hot air E in the engine room 12 from flowing into the vehicle side space 8.

Further , since the seal member 7 is fixed to the apron 4 to close the gap G, it is not necessary to extend the shoulder 4a of the apron 4, and it is not necessary to increase the size of the apron 4, thereby reducing costs. Can be

Furthermore, since the sealing member 7 is fixed to the apron 4, the engine hood 1 in an open state has always closed the gap G, the engine also open the engine hood 1 in an idling state of the engine room 12 Inside
Part of the hot air E is prevented from flowing into the vehicle-side space 8 from the gap G.

[0017] In addition, to form a recessed step 9 in elevation of the apron 4, by fixing the said sealing member 7 to the recessed step portion 9, elevation flush seal member 7 at least apron 4 Since the sealing member 7 does not protrude into the engine room 12 from the elevation of the apron 4,
There is no trouble that the seal member 7 is hooked off during the operation in the engine room 12, and the rigidity of the apron 4 is improved by forming the concave step portion 9.

[0018]

As described above, according to the present invention, the inflow of hot air into the vehicle side space in which the air intake of the intake duct is arranged is always prevented, and the rise of the intake air temperature of the engine is prevented.
In addition to improving engine efficiency, apron miniaturization,
This has the advantage that the cost can be reduced by shortening the length of the screw member, and obstacles during operation can be avoided .
