Abstract

PROBLEM TO BE SOLVED: To improve a seal performance by providing a step difference on the outer peripheral side of an end part of a seal rib having a large wall thickness so as to prevent an outer part of a packing from turning up from a vehicular body by pressing the packing and also prevent the entry of water to a seal requiring part side from a space between the packing and the vehicular body. SOLUTION: In this device, a wall thickness of a seal rib is partially large, and a step difference 12 is provided on the outside of an end part of the seal rib 11 having a large wall thickness. Therefore, an outer part of a packing 10 is prevented to turn up from a trunk lid 9 by pressing the packing 10 with the step difference 12 of the seal rib 11 having a large wall thickness, which enables reliably preventing water from entering a seal requiring part side from a space between the packing 10 and the trunk lid 9 to improve a seal performance. Since a repulsion force of the packing 10 is damped with the step difference 12 of the seal rib 11 having a large wall thickness, a problem of sliding a mount position of a rear combination lamp A to the trunk rid 9 caused by the repulsion force of the packing 10 can be prevented, so that the rear combination lamp A is precisely mounted at a fixed position on the trunk lid 9.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Two embodiments of a vehicle apparatus according to the present invention will be described below with reference to FIGS. 1 to 3 show a first embodiment of a vehicle device according to the present invention. In this example, a description will be given of a rear combination lamp attached to both right and left ends of a trunk lid as a vehicle device. In the drawings, the same reference numerals as those in FIGS. 6 to 8 denote the same components.

In the figure, reference numeral 11 'denotes a seal rib.
The seal rib 11 ′ has an annular shape, and is integrally provided outside the lamp chamber of the lamp housing 1 so as to surround a portion required for sealing. The thickness of a part of the seal rib 11 ′, in this example, the lower horizontal seal rib 11 is about twice as large as the thickness of the conventional seal rib 8. A step 12 is provided on the outer peripheral side of the end of the seal rib 11 having a large thickness (on the side opposite to the portion requiring sealing). The thickness of the inner peripheral side of the end of the seal rib 11 having a large thickness is
The thickness is about the thickness of the conventional seal rib 8.

Since the vehicle device of the present invention in this embodiment has the above-described configuration, as shown in FIGS. 2 and 3, an annular sealing rib 11 '(including the sealing rib 11 having a large thickness) is also included. The rear combination lamp A is attached to the trunk lid 9 with the packing 10 interposed between the end face of the trunk lid 9 and the end face of the seal rib 11 ′, which pushes the packing 10 toward the trunk lid 9. Crushing, and as a result, a sealing property is obtained. At this time, as shown in FIG. 3, the dimension P from the inner peripheral end surface of the thick seal rib 11 to the trunk lid 9 is about 2 mm, and the end surface of the conventional seal rib 8 and the trunk lid 9 are large. The packing 10 is crushed between the trunk lid 9 and the inner peripheral end face of the seal rib 11 having a large thickness, which is substantially equal to the dimension between the seal ribs 11, thereby ensuring the sealing performance.

In particular, in the vehicle device of the present invention, the packing 10 is pressed by the step 12 provided on the outer peripheral side of the end portion of the seal rib 11 having a large wall thickness. Thereby, it is possible to prevent the outer portion of the packing 10 from rolling up from the trunk lid 9. For this reason, as shown by a solid arrow W in FIG. 2, water that has entered the assembling space S between the rear combination lamp A and the trunk lid 9 penetrates into the portion where the seal is required from between the packing 10 and the trunk lid 9. Therefore, the sealing performance can be improved.

On the other hand, the lower packing rib 14 for preventing and reinforcing the packing 14 has, for example, a horizontal type (-type) and a vertical type (I type). The upper and lower ribs 13 and 14 for preventing and reinforcing the packing may be provided on at least one (upper or lower) side.

The vehicle device of the present invention according to the second embodiment can achieve the same operation and effect as the vehicle device of the present invention according to the first embodiment. In particular, since the vehicle device of the present invention in the second embodiment has the above-described configuration, as shown in FIG. 5, packing for preventing and reinforcing packing above and below the thick seal rib 11 is provided. Rib 1
Since the packing 10 can be prevented from dropping from the trunk lid 9 side to the lamp housing 1 side by 3 and 14, the outer portion of the packing 10 can be more reliably prevented from rolling up from the trunk lid 9. The sealing performance is further improved. Further, the strength of the lamp housing 1 is enhanced by the ribs 13 and 14 for preventing and reinforcing the packing from dropping on the upper and lower sides.

In the above-described embodiment, the rear combination lamp A of the vehicular lamp attached to the left and right ends of the trunk lid 9 is used as the vehicular device.
However, the present invention can also be used for other vehicular decorative devices such as other vehicular lamps and rear finishers. In the above-described embodiment, a rear finisher or the like may be integrally formed between the two rear combination lamps A attached to the left and right ends of the trunk lid 9.

Further, in the above-described embodiment, the seal rib 11 having a large thickness (and the ribs 13 and 14 for preventing and reinforcing the packing from dropping) is the annular seal rib 1.
