FIG. 7 is an enlarged view of the tail lamp 29 portion, and FIG. 1 is a sectional view taken along line AA of FIG. This
FIG. 1 shows a reference structure which is a premise of the embodiment.
The structure of FIG.
The common features such as structure and action will be described with reference to this drawing.

As is apparent from these figures, the tail lamp 29 is provided with a lens 60 having a substantially triangular shape in a plan view, and the lens 60 is formed as a hollow body and has a top portion 61, a side surface 62, a bottom portion 63, and a rear surface 64. And a front surface 65. The front and rear are based on the traveling direction. One shown in Figure 1
In the cross section of, the pair of side surfaces 62 facing each other are at the rear end of each other.
Connect at the rear face 62. These sides 62 are non-parallel to each other
And the distance between them becomes narrower toward the rear surface 64.
It forms a pair of changing lens surfaces.

Below the bottom portion 63, a discharge tube 66 which is long in the front-rear direction is provided. The long discharge tube 66 is used as a long continuous light source. However, the light source may be a point light source 67 such as a bulb, and both light sources are shown in FIG. FIG. 1 is a cross section substantially parallel to the bottom 63 facing these light sources.
Is shown.

As shown in FIG.
A transparent plating film 68 is applied to the inner surface of the side surface 62. The transparent plating film 68 is applied to the entire inner surfaces of the left and right side surfaces 62 and the rear surface 64 and the front surface 65.

However, the inner surface of the top portion 61 is a mirror surface, and the inner surface of the bottom portion 63 is a cut surface (see FIG. 8). The transparent plating film 68 has a property of reflecting a part of light and transmitting a part of the light.

The long discharge tube 66 is longer than the lens 60,
The front end side extends forward of the front face 65, and a plurality of reflectors 70, 71, 72 are provided surrounding the extended end. Each of the reflectors 70, 71, 72 has an angle at which the reflected light is directed inside the lens 60.

In this way, light that has passed through the bottom portion 63 from the long discharge tube 66 or the point light source 67 and has entered the lens 60 is reflected by the top portion 61 and is transmitted by the side surface 62, the rear surface 64, and the front surface 65. Part is transmitted by the plating film 68,
Some other part is reflected.

The reflected light is partially reflected and partially transmitted. Further, the light reflected by the reflectors 70, 71, 72 behaves similarly in the lens 60.

Since only the reflector 72 is provided with the transparent plating film 68, a part of the reflector 72 is transmitted and reflected by the reflector 71. In this way, the light finally emitted from the lens 60 is refracted and reflected in a complicated manner, so that almost the entire lens 60 emits light uniformly. Moreover, it is not parallel to each other in one cross section
The distance becomes narrower toward the rear surface 64, which is the connection end of each.
Since the side surface 62, which is a pair of lens surfaces, is provided,
Lens surface such as the rear surface 64 seen from the outside with complicated diffuse reflection
Can be uniformly emitted.

In addition, the shapes of the long discharge tube 66 and the point light source 67 are difficult to see, resulting in a deep emission state. In addition, the long discharge tube 66 or the point light source 67 is connected to the lens 60.
Since the lens 60 can be made to emit light regardless of whether it is located inside or outside, the degree of freedom in the shape and size of the lens 60, the type and arrangement of the light source, and the like are significantly increased.

[0034] Figure 8 is a real施例shows a cross section of a portion corresponding to the line C-C of FIG. In this example, a plurality of partition plates 73 that partition the inside of the lens 60 in the width direction are provided in the front-rear direction, and are arranged in parallel with each other and inclined rearward. Further, these partition plates 73 are not parallel to the side surface 62 which is a pair of lens surfaces which are not parallel to each other.

Each partition plate 73 is formed integrally with the lens 60, and as shown in the enlarged portion D, a transparent plating film 68 is applied to the surface thereof. However, each partition plate 73 is a lens 6
It may be provided separately from 0.

As shown in the enlarged portion E, the inner surface of the top portion 61 forms a mirror surface 74, and as shown in the enlarged portion F, the inner surface of the bottom portion 63 is a cut surface 75.

The other points are the same as in the previous embodiment, and the light source, for example, a point light source 67 is arranged below the bottom portion 63 as in the previous embodiment.

In this way, the point light source 67 is connected to the bottom 6
The light that has passed through 3 and enters the lens 60 is reflected by the top 61 and the side surface 62, the rear surface 64, the front surface 65, and the partition plate 7.
Through the transmission and reflection at 3, the side surface 62 and the rear surface 64 of the lens 60 are uniformly made to emit light. This point is the same as before, but in this embodiment, the light is more evenly dispersed. Moreover, the light source is directly visible through the lens
It gets harder. Also, the upper side is not parallel to the side surface 62, which is a pair of lens surfaces that are not parallel to each other, and the upper side tilts backward
Due to the presence of the plurality of partition plates 73 that are inclined rearward and are parallel to each other, the light can be more uniformly dispersed and more light is directed to the rear surface 64. Especially, the upper side
When the light is tilted backward so as to tilt backward, the amount of light toward the rear is increased , so that the range of dispersion and the distribution of the amount of light can be given directivity, and the tail lamp 29 is optimal.

FIG. 9 shows another embodiment, which shows a cross section similar to that of FIG. 1, in which a grid-like partition plate 76 is provided inside the lens 60 and is shown in the enlarged portion G. Further, the permeable plating film 68 is formed on the inner surface in the front-rear direction of each partition plate 76.
It is characterized in that it is given. In addition, applying the transparent plating film 68 to the inner surface of the side surface 62 is the same as before (enlarged portion H).

In this way, the reflection and refraction of light can be further complicated, so that more uniform light emission can be obtained.

FIG. 10 shows an embodiment applied to the front blinker 26 (see FIG. 1). In this embodiment, a lens 80 is fitted in a corner portion formed by the inner cowl 10a that bends inwardly of the vehicle body at a part of the front cowl 9 and the tip of the front cowl 9, and the inner surface of the lens 80 is the same as before. A transparent plating film 68 is applied.

The valve 81 is provided at a position retracted toward the inner cowl 10a, and a main body reflector 82 is provided so as to surround the rear of the valve 81.

The inner surface of the main body reflector 82 is the mirror surface 8
It is 3. Further, a semi-transparent reflector 84 having a substantially U-shaped cross section is provided in front of the main body reflector 82.

The semi-transparent reflector 84 is made of a base made of a transparent material and has a transparent plating film 68 applied to the inner surface thereof, and surrounds the bulb 81. In addition, this
Also in the embodiment of FIG.
0 is non-parallel and spaced from each other towards the connecting ends
Is provided with a pair of lens surfaces that become narrower.

With this structure, part of the light from the bulb 81 is transmitted through the semi-transmissive reflector 84 and reflected by the mirror surface 83 of the main body reflector 82, or is directly reflected by the lens 8
The lens 80 is caused to emit light uniformly through various paths such as toward the 0 direction.

At this time, if the semi-transmissive reflector 84 does not exist, the presence of the step 85 of the inner cowl 10a causes a portion 86 where the light quantity is weakened only by the reflected light from the side of the mirror surface 83. Sex reflector 84
Accordingly, since it is possible to increase the amount of this portion, to eliminate such portions, can be made uniform across the emitting light.
