The rear combination lamp 101 includes a housing 107 connected to a vehicle body panel 105 by bolts 103, a reflector 109 provided outside the housing 107, and a lens 111 provided outside the reflector 109. A fitting hole 113 is formed in the housing 107, and a socket 115 is fitted in the fitting hole 113. The socket 115 is formed in a substantially cylindrical shape, and an illumination bulb 117 is attached to an inner diameter portion of the socket 115. The reflector 109 has a hole 119 formed therein. The bulb 117 fitted in the hole 113 projects through the hole 119 to the outside of the reflector 109, and the lens 111 covers the bulb 117.

To assemble the rear combination lamp 101, the positions of the fitting hole 113 and the hole 119 are aligned, the reflector 109 is connected to the housing 107, the lens 111 is mounted from outside, and the lens 111 is mounted on the housing 107. Combine and do. A protrusion 112 is formed on the peripheral edge of the lens 111, and the protrusion 112 is fitted into a recess 108 formed in the housing 107, and this portion is sealed by a hot melt 120. The rear combination lamp 101
The front end 109a of the reflector 109 is attached to the end 11
When the lens 1a is formed to a position close to the inner surface, the lens 111
Cannot be easily assembled. Therefore, in order to facilitate the assembling operation of Le <br/> lens 111, the tip 109a of the reflector 109 is not provided position to close the end portion 111a inside surface of the lens 111.

However, the rear combination lamp 1
Reference numeral 01 denotes a lens which is formed to have a shape which extends from the rear side of the vehicle body to the side for the reason of vehicle body formation.
1 is used. Therefore, the end 111 of the lens 111
a is viewed obliquely from the rear (in the direction of the arrow Q in FIG. 4), the back surface of the reflector 109, the housing 107, etc.
11 may be seen from the outside, and the appearance from the direction of arrow Q will be poor. When the inside of the rear combination lamp 101 is vertically divided by the reflector,
There is a possibility that a cavity may be formed between the top and bottom of the lens 111 and the end of the lens 111 to cause light leakage.

On the other hand, in the rear combination lamp 121 shown in FIG. 5, the reflector 122 is not connected to the housing 107 but is engaged with the lens 111 by a clip or the like (not shown). Therefore, the tip 122 a of the reflector 122 is connected to the end 1 of the lens 111.

[0007]

However, in such a combination lamp 121, the reflector 1
Since the reflector 22 is not completely fixed, the reflector 122 may slightly move due to the vibration during the running of the vehicle, and the tip 122a of the reflector 122 may come into contact with the lens 111, so that abrasion powder of the two may be generated. In order to prevent this, a method of completely fixing the reflector 122 to the lens in advance is conceivable, but in this case, the positioning of the hole 119 with respect to the fitting hole 113 becomes uncertain, and the valve 11
There is a possibility that the assembling accuracy of the reflector 7 and the reflector 122 may be reduced. If the assembly accuracy between the bulb 117 and the reflector 122 is reduced, the light distribution from the bulb 117 may be adversely affected.

Therefore, according to the present invention, the assembling work is easy,
An object of the present invention is to provide a rear combination lamp that has good appearance and does not generate abrasion powder due to slight movement of a reflector.
