DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, an opening 4 is formed in the outer panel 2 at a high position on the rear surface of the vehicle, and a notch 8 having a wider front opening than the opening 4 is formed in the inner panel 6. Then, the high mount stop lamp 10 is attached by being inserted from the cutout portion 8. The high mount stop lamp 10 is composed of a housing 14 which houses a bulb 12 therein, and a lens 16 which is mounted in a front end opening of the housing 14. As shown in FIG. 2, the housing 14 has a flange portion 18 at the front end opening and mounting portions 20, 20 on both sides in the vehicle width direction. A bolt insertion hole 22 is formed in each mounting portion 20, and is fixed with a bolt 24.

An end rubber 26 as an elastic member is provided on the side wall of the high mount stop lamp 10 on the side of the lens 16 over the entire circumference. End rubber 2
As shown in FIGS. 1 and 3, 6 is formed in a U-shaped cross section having a hollow portion 28 therebetween. In other words, one side 30 protruding outward of the outer panel 2 and the one side 30
And the other side 32 that is folded back inward from the outer panel 2. The free end portion 30a of the one side 30 is fixed to the flange portion 18 of the housing 14 by means such as adhesion, and most of the other side 32 is also fixed to the outer peripheral side surface of the lens 16. Further, on the outer surface of the one side 30, the groove 3 as an engaging portion into which the peripheral edge 4a of the opening 4 closely enters.
4 is formed, and the groove 34 has an outer pressing portion 30b along the outer surface of the outer panel 2 and an outer pressing portion 30b.
It is partitioned by a longer inner holding portion 30c.

The high mount stop lamp 10 is fixed to the vehicle body by closely fitting the end rubber 26 in the opening 4 of the outer panel 2 and fixing the housing 14 to the inner panel 6. To fix the housing 14 to the inner panel 6, as shown in FIG. 4, the mounting portion 20 of the housing 14 is aligned with the fixing hole 6a formed at a predetermined position of the inner panel 6 and is tightened with the bolt 24 and the nut 36. . In this case, the inner panel 6 may be configured to have a working opening to hold the nut 36. Alternatively, the nut 36 may be fixed to a predetermined position of the inner panel 6 in advance, and the positional deviation may be caused by the bolt insertion hole 22 of the mounting portion 20. The configuration may be adjusted by the shape of the long hole. In FIG. 4, reference numeral 38 indicates a washer.

Next, the mounting operation will be described. End rubber 2
The high mount stop lamp 10 integrally provided with 6 is inserted from the notch 8 of the inner panel 6, and before the lens 16 is positioned in the opening 4, as shown in FIG.
Using, to press the end rubber 26 with your finger to bend it,
In this state, the groove 34 is engaged with the peripheral edge 4a of the opening 4. When the pressed state is released, the end rubber 26 elastically restores and automatically fits into the opening 4 in a close contact state as shown in FIG.

Even if the accuracy of assembly of the outer panel 2 varies, the error is absorbed by the bending deformation of the end rubber 26, so that the surface of the lens 16 with respect to the outer panel 2 can be immediately obtained by a simple operation of pushing and mounting. . Moreover, since airtightness is obtained at the same time, a good waterproof state can be obtained. That is, the end rubber 26
Has both the functions of the conventional packing and the extension cover. Therefore, it is possible to facilitate the management of parts and improve handling by reducing the number of parts. Further, since the end rubber 26 is separated from the function of fixing the housing 14 to the inner panel 6, an extension portion for fixing the bolt unlike the conventional extension cover is not necessary, and the end rubber 26 is constant over the entire circumference of the lens 16. Has a width of. As a result, the amount of exposure to the outside is reduced as much as possible, balance on the contour with a constant width is obtained, and the appearance is improved. On the other hand, since the inner pressing portion 30c is longer than the outer pressing portion 30b,
Sufficient waterproof function will be obtained. That is, consideration is given to both the appearance and the waterproofness of the engaging portion.

Housing 14 for inner panel 6
Since it is fixed independently of the end rubber 26, it is not necessary to form a bolt insertion hole in the outer panel 2 as in the conventional case as shown in FIG. There is no need to worry about such waterproofing.

In the above example, an example in which a high mount stop lamp is attached has been shown, but the present invention is not limited to this and is similarly applicable to other vehicle lamps. Further, although the shape of the end rubber as the elastic member and its fixing form to the vehicle lamp are specified, the present invention is not limited to this, and is within a range in which the so-called one-touch mounting and the close fitting function by the bending deformation can be obtained. The design can be changed appropriately.

[0017]

According to the present invention, the space between the lens of the vehicle lamp and the vehicle body panel is closed by a flexible deformable elastic member engaging with the opening of the vehicle body panel. Therefore, the error of the vehicle body accuracy is absorbed by the hollow portion, and the elastic member is surely fitted to the opening regardless of the variation of the vehicle body accuracy. As a result, the surface of the lens can be easily aligned with the opening and the waterproof function can be obtained. Further, since the face-to-face matching and the fixing with respect to the opening can be immediately obtained by a simple push-engagement operation of the elastic member, the efficiency of the mounting work can be improved.

According to the third aspect of the present invention, since the engaging portion is formed in a groove shape, the waterproof function can be further improved by fitting the opening portion of the vehicle body panel into the engaging portion. . According to the invention of claim 4, since the engaging portion is formed in a groove shape on one side of the elastic member, the hollow portion of the elastic member is surely bent, and the vehicle lamp and the vehicle body due to poor assembly accuracy of the vehicle body. The error of can be absorbed. Claim 5
According to the described invention, the waterproof function of the high mount stop lamp can be further improved.
