The tail lamp / brake light 3 and the backward light 4 are configured as an integrated lamp, which is similar to the conventional example.

For the purpose of facilitating the confirmation of the width of the vehicle body 20 with respect to the following vehicles, the direction indicator lamp 2 and the tail lamp / braking lamp 3 are located on the side surface of the vehicle body 20 in the left and right rear combination lamps 1. This is also the same as the conventional example in that the backward light 4 is provided at a position nearer to 22 so that the backward light 4 is provided at a position closer to the center.

Here, in the present invention, the backward light 4 is used.
Is not simply provided near the center as in the conventional example, but is strictly provided in contact with the end near the center of the rear combination lamp 1. That is,
This rear combination lamp 1 has a rear end face 21 of the vehicle body.
When viewed from the side, the right end is provided in contact with the right end, and the right end is provided in contact with the right end.

In addition to the above, in the rear combination lamp 1 of the present invention, the lens surface 4a of the portion contacting the end of the retreat lamp 4 is bent toward the vehicle body 20 side in a direction substantially parallel to the side surface 22 of the vehicle body 20. Shaped inclined lens surface 4b
Is provided. Therefore, when the left and right rear combination lamps 1 are attached to the vehicle body 20, the inclined lens surfaces 4b face each other.

When providing the inclined lens surface 4b, when the rear end surface 21 is substantially flat, the rear combination lamp 1 is provided at a portion near the center of the rear end surface 21 in order to provide the inclined lens surface 4b. It is necessary to form the lens surface of the rear side of the rear combination lamp 1 at an appropriate amount, but as described in the conventional example, the number plate 2 is usually provided between the left and right rear combination lamps 1 at the rear end 21.
Since the concave portion 21a for accommodating 3 is provided,
The inclined lens surface 4b may be provided by using the recess 21a.

The reversing lamp 4 is provided with a lens surface 4a, a light source 4c, a reflecting mirror 4d, and the like on the left and right sides 4 as in the conventional example.
At the same time as generating light distribution up to 5 °, the inclined lens surface 4
The light distribution in the direction substantially orthogonal to the inclined lens surface 4b is also generated at the same time, for example, by direct light from the light source 4c that transmits b.

FIG. 3 shows a state of light distribution by the inclined lens surface 4b. The rear combination lamp 1 is provided with the inclined lens surface 4b at the end portion near the center thereof, so that the rear combination If the lamp 1 is for the right side, the light from the inclined lens surface 4b is to illuminate the left side surface immediately after the vehicle body 20, and if it is for the left side, it is the right side surface immediately after the vehicle body 20.

That is, the light from the respective inclined lens surfaces 4b intersects immediately after the vehicle body 20 and illuminates the side opposite to the side where the rear combination lamp 1 is installed. Although FIG. 3 shows only the irradiation light from the inclined lens surface 4b in order to clearly show the function of the inclined lens surface 4b, in the actual rear combination lamp 1, the irradiation from the lens surface 4a is shown. The light is also duplicated.

At this time, the inclined lens surface 4b
In order to improve the visibility, it is possible to provide an appropriate light diffusing means such as a prism cut so as to maintain continuity so that the light distribution from the lens surface 4a and the brightness are not extremely stepped. It is also preferable from the aspect. In addition, if necessary, the auxiliary reflecting surface 4 corresponding to the inclined lens surface 4b.
It is free to implement means such as providing e (see FIG. 2) and increasing the amount of light from this inclined lens surface 4b.

FIG. 4 shows the light distribution characteristic H of the rear combination lamp 1 of the present invention. In the conventional one, there is substantially no light on the left and right sides immediately after the vehicle body 20. On the other hand, with the above configuration, an illuminance of 1.0 (lux) or more can be obtained even at a position approximately 1 m laterally and approximately 1 m rearward from the vehicle body 20 shown by a point P in the drawing.
