Embodiments of the present invention will now be described in detail with reference to the drawings.

A perspective view of the front left half of the vehicle is shown in FIG. A bonnet hood 1 including a hood outer panel 1a and a hood inner panel 1b (see FIG. 2 or 5) is provided so as to cover an engine room formed in the vehicle body. An apron reinforcement 7 including an apron reinforcement upper panel 2 and an apron reinforcement lower panel 3 extending in the vehicle front-rear direction is disposed below and to the left and right of the hood 1 of the hood. At the lower end of this apron reinforcement 7, a wheel house (not shown),
A wheel apron 4 on which a suspension tower (not shown) is formed is joined.

The hood 1 is supported on the vehicle body by a hinge (not shown) so as to be openable and closable. A striker (not shown) and a latch (not shown) as a lock device for holding the hood 1 in the closed state are provided between the vehicle body and the hood 1.

A sectional view of the bonnet hood 1 at the D position in the closed state is shown in FIG. The apron reinforcement 7 is installed so as to project outward in the vehicle width direction,
The front fender panel 5 is joined to the apron reinforcement 7 so that the vertical wall 10 is formed at the vehicle width direction outer end of this upper surface portion.
A seal surface 6 is formed on the inner surface of the vertical wall 10 from the root portion thereof toward the inner side in the vehicle width direction. By the way, this sealing surface 6
Is provided for the purpose of sealing and is also provided so that the inside of the engine room cannot be seen through the gap formed between the front fender panel 5 and the hood 1 of the hood.

An outer flange 9 is formed on the bonnet outer panel 1a, and an inner flange 8 is formed on the bonnet inner panel 1b. The outer side flange 9 is formed with a hem portion 11 as a support portion that wraps around so as to cover the tip of the inner side flange 8, and the bonnet outer panel 1a and the bonnet inner panel 1b are joined together by this hem portion 11 to be integrated. .

The seal member 12 has a seal mounting portion 13
And a seal portion 14, and a seal mounting portion 13
The hem portion 11 is fitted into the hood 1 and the seal member 12 is attached to the bonnet hood 1. A seal portion 14 is provided at the tip opposite to the side where the hem portion 11 is fitted, and the seal portion 14 abuts the seal surface 6 to achieve the seal between the engine room and the outside of the vehicle.

The seal structure between the vehicle body and the hood 1 is constructed as follows in the first embodiment of the present invention. The height 1 of the gap 15 between the hood 1 and the sealing surface 6 shown in FIG.
Positions A, C, D, shown in FIG. 3 with respect to D, E, B
The heights E and B are set so as to correspond to the respective heights l. At this time, 1 in the middle D of AB is set to the maximum. This is because the lift in the middle D is maximum. Moreover, 1 is gradually reduced from the intermediate D as a starting point toward A and B which are positions corresponding to the hinge or the lock device.

Since the gap 15 is maximized at the intermediate portion between the hinge and the locking device and is formed so as to gradually decrease toward the hinge and the locking device, the bonnet hood 1 corresponding to the intermediate portion is separated from the seal member 12. Even if it is only trying to lift up due to the reaction force, the rising amount is offset by increasing the gap portion 15, so that there is a step with the vehicle body over one circumference of the hood. Can be prevented.

The seal structure between the vehicle body and the hood 1 is constructed as follows in the second embodiment of the present invention. The hood 17 shown in FIG. 5 is provided with a seal member 18. The height of the seal portion 20 continuously provided to the seal member 18 is set to the positions A, C shown in FIG.

It is set in correspondence with each height d of E and B. C formed small height portion 16, as D, the d of the small height portion 16 in the intermediate D in AB of E shown in FIG. 5 (a), in the closed state of the bonnet hood 17, taken seal
A gap formed between the tip of the attachment part 19 and the sealing surface
The height is substantially the same as that of, and is set to the minimum between positions A and B. The intermediate D is used as a starting point and d is gradually increased toward A and B, which are positions corresponding to the hinge or the lock device shown in FIG. 5B.

Since the low-back portion 16 is formed so as to be the smallest in the intermediate portion between the hinge and the locking device and gradually increases toward the hinge and the locking device, the bonnet hood 17 corresponding to the intermediate portion is separated from the seal member 18. Even if only the reaction force tries to lift up, the lifted amount is offset by lowering the low back portion 16, so that there is a step with the vehicle body around the bonnet hood 17. Can be prevented.

The configuration in which the gap portion 15 and the low back portion 16 are gradually changed is more effective when used in the hood 17 shown in FIG. The hood 17 is a hood outer panel 17 made of aluminum.
a and a bonnet inner panel 17b, and a honeycomb 21 is arranged in a closed cross section formed between the two panels 17a and 17b. This is to reduce the weight and prevent noise from the bonnet itself (reduce transmitted sound). However, in this case, the rigidity of the bonnet hood 17 as a single body may be lower than that of the conventionally used bonnet hood 1. Therefore, when the bonnet hood 17 is provided on the vehicle body, it is considered that a step between the bonnet hood 17 and the vehicle body appears more prominently.

In this embodiment, the seal members 12, 1
Although only the structure in which 8 is attached to the bonnet hoods 1 and 17 is shown, a seal member may be attached to the vehicle body. In this case, as shown in FIG. Flange 2 as a support portion provided on the front fender panel 5
If they are provided so as to be overlapped with 3, the sound leakage between the front fender panel 5 and the cowl 22 can be prevented. Further, as shown in FIG. 7, the flange 23,
