The outer incident portion 124 includes a straight portion 124a that extends substantially straight forward from a position close to the front surface of the outer one-color light source 100, and a curved portion 124b that curves in the vehicle width direction on the front end side.
The light guided through the inner incident portion 122 and the outer incident portion 124 is almost totally reflected by the straight portions 122a and 124a, but a part of the light leaks from the curved portions 122b and 124b, and the amount of light is attenuated.

  The lower light guide portion 123 is provided with a light diffusion portion 123a that diffuses light guided through the lower light guide portion 123 forward. The light diffusion part 123 a is a lens cut part on the surface part of the lower light guide part 123, for example. As light diffuses in the light diffusion portion 123 a, light passing through the lower light guide portion 123 is emitted to the front of the lower light guide portion 123. The light incident on one end of the lower light guide member 121 is attenuated by the light diffusion portion 123a when proceeding to the other end side in the lower light guide member 121, and the amount of light gradually decreases.

The light guide lens 72 includes a claw-like locking piece 132 that extends outward from the rear end portion of the outer incident portion 114 and the outer incident portion 124 in the vehicle width direction.
FIG. 9 is a plan view of the center part in the vehicle width direction of the left and right light guide lenses 72, 72 as viewed from above.
Although the left and right light guide lenses 72 and 72 have been described as being symmetrical, the configuration in the center in the vehicle width direction is different on the left and right.
Referring to FIGS. 7 and 9, the left light guide lens 72 extends from the inner side surfaces of the rear ends of the inner incident portion 112 and the inner incident portion 122 to the inside in the vehicle width direction, and then extends forward. 133 is provided.

As shown in FIG. 9, the right light guide lens 72 includes an other leg portion 134 that extends inward in the vehicle width direction from the inner side surfaces of the rear ends of the inner incident portion 112 and the inner incident portion 122 and then extends forward. And a plate-like seating surface portion 135 extending from the front end of the other side leg portion 134 to the one side leg portion 133 side. The seat surface portion 135 is formed with a hole 135a penetrating in the front-rear direction.
The one side leg portion 133 receives a side portion opposite to the other side leg portion 134 on the rear surface of the seating surface portion 135. The one side leg part 133, the other side leg part 134, and the seat surface part 135 constitute a center side fixing part 136 that is fixed to the boss part 80b.

As shown in FIG. 3, the light guide lens 72 is disposed so as to cover the rear member front surface 83 from the front, and the inner incident portion 112 and the inner incident portion 122 are located in front of the hollow portion 80 in the center in the vehicle width direction of the housing 73. Plugged in. Further, the outer incident portion 114 and the outer incident portion 124 are inserted into the hollow portion 81 at the outer end portion in the vehicle width direction of the housing 73 from the front.
The light guide lens 72 is fixed to the housing 73 via the center side fixing part 136, the upper side fixing part 130, the lower side fixing part 131 and the locking piece 132. Specifically, the center side fixing portion 136 is fixed to the boss portion 80b (FIG. 5) by a fixing bolt 137 inserted through the hole 135a of the seat surface portion 135. The upper fixing portion 130 is fastened together with the fixing portion 87 by a fixing bolt 89b. The lower fixing portion 131 is fastened together with the fixing portion 88 by a fixing bolt 89b. The locking piece 132 is locked in the locking hole 81c (FIG. 5).

3, 5, and 7, the direction indicator lamp unit 71 serves as a light source for causing the light guide lens 72 to emit light, and as described above, the inner one color arranged vertically at the vehicle width direction inner side position as described above. A light source 90 and an inner other color light source 91 are provided, and an outer other color light source 101 and an outer one-color light source 100 are vertically arranged at positions outside the vehicle width direction.
In this arrangement, the inner one-color light source 90 and the outer one-color light source 100 are in a diagonal positional relationship. Further, the inner other color light source 91 and the outer other color light source 101 are in a diagonal positional relationship. That is, in the first embodiment, light sources that emit light of the same color are arranged in a diagonal positional relationship. Light sources that emit light of different colors are connected in the vehicle width direction by the upper light guide member 111 and the lower light guide member 121.

When the upper light guide member 111 emits light in one color (orange), the inner one-color light source 90 emits light. In this case, the light emitted from the inner one-color light source 90 enters the inner incident portion 112 at one end, emits light forward when passing through the upper light guide portion 113, passes through the outer incident portion 114 at the other end, and passes through the other outer color. The light source 101 is reached.
When the upper light guide member 111 emits light in another color (white), the outer other-color light source 101 emits light. In this case, the light emitted from the other external color light source 101 enters the outer incident portion 114 at one end, emits light forward when passing through the upper light guide portion 113, passes through the inner incident portion 112 at the other end, and passes through one inner color. The light source 90 is reached.

When the lower light guide member 121 emits light in one color (orange), the outer one-color light source 100 emits light. In this case, the light emitted from the outer one-color light source 100 enters the outer incident portion 124 at one end, emits light forward when passing through the lower light guide portion 123, passes through the inner incident portion 122 at the other end, and passes through the inner other portion. A color light source 91 is reached.
When the upper light guide member 111 emits light in another color (white), the inner other-color light source 91 emits light. In this case, the light emitted from the inner other-color light source 91 enters the inner incident portion 122 at one end, emits light forward when passing through the lower light guide portion 123, passes through the outer incident portion 124 at the other end, and goes outside. A single color light source 100 is reached.

Thus, since the inner one-color light source 90 and the outer other-color light source 101 capable of entering different colors are provided at both ends (one end and the other end) of the upper light guide member 111, one upper light guide with a simple structure. Different colors can be emitted from the member 111.
Similarly, since the inner other color light source 91 and the outer one-color light source 100 capable of entering different colors are provided at both ends (one end and the other end) of the lower light guide member 121, one lower guide with a simple structure is provided. Different colors can be emitted from the light member 121.

The direction indicator lamps 62 and 62 emit light in one color (orange) when used as a direction indicator lamp, and emit light in another color (white) when used as a position lamp.
When the direction indicator lamps 62 and 62 are used as direction indicator lamps, the light control unit 67 causes the inner one-color light source 90 and the outer one-color light source 100 to emit light and does not cause the outer other-color light source 101 and the inner other-color light source 91 to emit light (extinguishes). To do). The light control unit 67 mixes the light sources 90 and 100 of one color and the light sources 91 and 101 of other colors and does not emit light at the same time.
Accordingly, as shown in FIG. 7, in the upper light guide member 111, the light emission L <b> 1 of the inner one-color light source 90 is guided outward in the vehicle width direction to the outer other color light source 101 side, and in the lower light guide member 121, The light emission L2 of the outer one-color light source 100 is guided to the inner other color light source 91 side in the vehicle width direction inner side. That is, when the direction indicating lamps 62 and 62 are used as direction indicating lamps, the light guide lens 72 emits light of one color (orange) from both sides in the vehicle width direction so as to pass in the vehicle width direction.

  The one-color light emission L1 guided from the inner one-color light source 90 to the upper light guide member 111 is attenuated and becomes weaker toward the outside in the vehicle width direction, but this attenuation is the light emission L2 of the outer one-color light source 100. Supplemented by. Further, the light emission L2 of one color guided from the outer one-color light source 100 to the lower light guide member 121 is attenuated and becomes weaker as it goes inward in the vehicle width direction. Of light emission L1. For this reason, the direction indicator lamp 62 can emit light satisfactorily over the entire vehicle width direction.

When the direction indicating lamps 62 and 62 are used as position lamps, the light control unit 67 causes the outer other color light source 101 and the inner other color light source 91 to emit light, and does not cause the inner one color light source 90 and the outer one color light source 100 to emit light (turns off). ).
Thus, in the upper light guide member 111, the light emission L3 of the outer other color light source 101 is guided to the inner one color light source 90 side inward in the vehicle width direction, and the lower light guide member 121 emits light of the inner other color light source 91. L4 is guided outward in the vehicle width direction toward the outer one-color light source 100 side. That is, when the direction indicating lamps 62 and 62 are used as position lamps, the light guide lens 72 emits light of other colors (white) from both sides in the vehicle width direction so as to pass in the vehicle width direction.

  The light emission L3 of the other color guided from the outer other color light source 101 to the upper light guide member 111 is attenuated and becomes weaker as it goes inward in the vehicle width direction. Of light emission L4. The light emission L4 of the other color guided from the inner other-color light source 91 to the lower light guide member 121 is attenuated and becomes weaker as it goes to the outer side in the vehicle width direction. It is supplemented by the light emission L3 of the color light source 101. For this reason, the position lamp can emit light satisfactorily over the entire vehicle width direction.

As shown in FIGS. 3 and 6, the inner light source unit 74 and the outer light source units 75 and 75 are such that the inner substrate 93 and the outer substrate 103 face the front surface on which the light sources 90, 91, 100, and 101 are provided. It is arranged to stand. For this reason, the direction indicator lamp unit 71 can be formed compactly in the front-rear direction. In this configuration, since the light emission direction of the light sources 90, 91, 100, 101 is forward, in order to guide the light to the upper light guide member 111 and the lower light guide member 121 extending in the vehicle width direction, the curved portion 112b, 114b, 122b, and 124b need to be provided. Although light is attenuated at the curved portions 112b, 114b, 122b, and 124b, in the first embodiment, as described above, light of the same color passes from both sides in the vehicle width direction so as to pass in the vehicle width direction. Since it is emitted, the influence of attenuation can be compensated. For this reason, it is possible to achieve both compactness of the direction indicator lamp unit 71 and good light emission.
Further, since the inner light source unit 74 and the outer light source units 75 and 75 are arranged separately in the vehicle width direction, the heat of the inner light source unit 74 and the outer light source units 75 and 75 can be efficiently exhausted, and the inner light source unit 74 can be exhausted. And it can suppress that the outer side light source units 75 and 75 become high temperature.

FIG. 10 is a schematic diagram for explaining the reflection of light from the outer one-color light source 100.
7 and 10, when the direction indicator lamps 62 and 62 are used as position lamps, the inner other color light source 91 is caused to emit light, and the other color (white) emission L4 of the inner other color light source 91 is emitted to the outer side. The light reaches the one-color light source 100 and is reflected by the outer one-color light source 100.
Since the outer one-color light source 100 includes a single-color phosphor 100a for emitting one color (orange), when the other-color (white) light emission L4 is reflected by the phosphor 100a, the reflected light L5 is one-color (orange). ).
In the first embodiment, since the inner other color light source 91 and the outer other color light source 101 are arranged in a diagonal relationship, the reflected light L5 is the outer other color light source adjacent to the outer one color light source 100. It becomes inconspicuous by the strong light emission of 101. For this reason, the position lamp can emit light with a favorable single other color (white). The same effect can be obtained with the inner one-color light source 90, the inner other-color light source 91 and the outer-other-color light source 101 of other colors.

FIG. 11 is a schematic diagram showing the lighting state of the direction indicator lights 62 and 62. FIG. 11A shows a state where it is used as a position lamp. FIG. 11B shows a state where the right direction indicator lamp 62 is used as a direction indicator lamp. FIG. 11C shows a state where the left direction indicator lamp 62 is used as a direction indicator lamp.
During normal running of the motorcycle 1, as shown in FIG. 11A, the left and right direction indicator lights 62 and 62 are lit as position lamps and emit light in other colors (white).

Upon receiving a command to turn on the right direction indicator lamp 62, the light control unit 67 turns on the right direction indicator lamp 62 and turns off the right position lamp as shown in FIG. 11B. The indicator lamp 62 is kept on as a position lamp. That is, in the right direction indicator lamp 62, the orange inner one-color light source 90 and the outer one-color light source 100 are turned on, and the white inner other-color light source 91 and the outer other-color light source 101 are turned off.
As described above, when the right direction indicator lamp 62 is turned on as the direction indicator lamp, the right position lamp is turned off, and thus the visibility of the right direction indicator lamp 62 is good.
Upon receiving a command to turn on the left direction indicator lamp 62, the light control unit 67 turns on the left direction indicator lamp 62 and turns off the left position lamp as shown in FIG. 11C. The indicator lamp 62 is kept on as a position lamp.

FIG. 12 is a diagram showing a state in which the lighting directions of the direction indicating lamps 62 and 62 are viewed from a plurality of different directions on the front side. FIG. 12A is a view as seen from the front side. FIG. 12B is a view as seen from the left side of the vehicle. FIG. 12C is a view as seen from the right side of the vehicle.
In FIG. 12, the left direction indicator lamp 62 is lit as a direction indicator lamp. Here, assuming that the side where the direction indicator lamp 62 is lit is the inside in the vehicle width direction, FIG. 12B is a view seen from the inside in the vehicle width direction, and FIG. It is the figure seen from the outside.

The direction indicator lamp 62 emits light strongly at a portion close to the light source that emits light. When used as the direction indicator lamp 62, the inner one-color light source 90 and the outer one-color light source 100 emit light, and both end portions in the vehicle width direction of the direction indicator lamp 62 in which these light sources are located are particularly easily visible due to strong light emission. .
When the direction indicator lamp 62 is viewed from the front side as shown in FIG. 12A, both the strong light emitting part 62a of the inner one-color light source 90 and the strong light emitting part 62b of the outer one-color light source 100 are visually recognized. Visibility is good.

Since the direction indicator lamp 62 includes the light guide lens 72 and is inclined outward and rearward in the vehicle width direction, the direction indicator lamp 62 is viewed from the front in the vehicle width direction as shown in FIG. When viewed, the strong light emitting portion 62a of the inner one-color light source 90 is in a position where it is easily visible, and visibility is good.
Since the direction indicator lamp 62 includes the light guide lens 72 and is inclined outward and rearward in the vehicle width direction, the direction indicator lamp 62 is viewed from the front in the vehicle width direction outer side as shown in FIG. When viewed, the strong light emitting portion 62b of the outer one-color light source 100 is in a position where it can be easily seen, and visibility is good.
As described above, since the direction indicator lamp 62 includes the light guide lens 72 and is inclined toward the outer side in the vehicle width direction and the rear upper side, the front side of the direction indicator lamp 62 from the inner side to the outer side in the vehicle width direction At least one of the strong light emitting part 62a and the strong light emitting part 62b can be visually recognized over a wide range. For this reason, the visibility of the direction indicator lamp 62 is good. Even if the direction indicator lamp 62 is used as a position lamp, the same effect can be obtained.

13 is a cross-sectional view of the direction indicator lamp unit 71 in FIG. 3 taken along the line XIII-XIII.
Referring to FIGS. 3, 5, and 13, the rear member front surface 83 of the housing 73 is provided to be inclined rearward in a side view, and is inclined rearward from the vertical as a whole. The housing 73 is a rear member that covers the upper light guide member 111 and the lower light guide member 121 from the rear.
The housing 73 is a reflecting member that reflects light and a design member that is visually recognized from the outside through the transparent outer lens 70. A silver decorative layer is formed on the surface of the rear member front surface 83 of the housing 73 in order to improve the design of the direction indicator lamp unit 71.
The recessed portion 86 of the rear member front surface 83 is formed in a valley shape that is recessed in a substantially V shape toward the rear side. The recess 86 has an upper reflecting surface 86a that is inclined rearwardly downward from the upper part of the front surface 83 of the rear member and extends rearward, and a lower surface that is inclined rearwardly upward from the lower part of the front surface 83 of the rear member and extends rearward. The side reflection surface 86b (recessed inclined surface) and a bottom portion 86c where the rear end of the upper reflection surface 86a and the rear end of the lower reflection surface 86b merge.
In the side view, the lower reflective surface 86b is formed longer than the upper reflective surface 86a.

  Since the recess 86 is covered from the front by the light guide lens 72, the recess 86 is hardly visible from the front. The light guide lens 72 including the upper light guide member 111 and the lower light guide member 121 is a transmissive member that transmits light.

  Sunlight falls on the motorcycle 1 from above. In general, when sunlight is radiated from the front upper side of the vehicle headlamp, the reflected light reflected by the reflecting surface of the headlamp is radiated forward, and the headlamp emits light. It becomes difficult to be seen by people around the motorcycle 1.

In FIG. 13, the conventional reflecting surface 283 is indicated by phantom lines. The conventional reflecting surface 283 is formed in a backward inclined flat plate shape.
When sunlight S1 enters the conventional reflecting surface 283 obliquely from the front upper side, the reflected light R1 is emitted forward substantially horizontally. For this reason, the reflected light R <b> 1 easily reaches the surrounding people and the like, the light emission of the light guide lens 72 itself becomes inconspicuous, and the visibility of the light emission of the light guide lens 72 is lowered.

  In the rear member front surface 83 of the first embodiment, when sunlight S2 is incident on the recess 86 obliquely from the front upper side, the sunlight S2 is reflected by the lower reflection surface 86b that is the lower wall portion in the recess 86. The reflected light R2 is emitted obliquely forward and upward. For this reason, it is difficult for the reflected light R2 to reach the surrounding people and the like, the light emission of the light guide lens 72 itself can be conspicuous, and the light emission visibility of the light guide lens 72 is good. Here, sunlight S1 and sunlight S2 are the same incident angle.

As described above, according to the first embodiment to which the present invention is applied, the direction indicator lamps 62 and 62 that are vehicle lamps include the inner one-color light source 90 and the outer other-color light source 101 made of semiconductor elements, And an upper light guide member 111 that guides light from the light source incident on the inner incident portion 112 on one end and the outer incident portion 114 to the other end, and different colors (orange, white) on both ends of the upper light guide member 111. ) And an outer other color light source 101 are provided. Further, the direction indicator lamps 62 and 62 guide the light of the light source that is incident on the outer one-color light source 100 and the inner other-color light source 91 made of semiconductor elements, and the outer incident portion 124 and the inner incident portion 122 at one end to the other end. The lower light guide member 121 includes an outer one-color light source 100 and an inner other-color light source 91 that can enter different colors (orange and white) at both ends of the lower light guide member 121, respectively.
Accordingly, different colors can be incident on the upper light guide member 111 from the inner one-color light source 90 and the outer other-color light source 101 that are light sources at both ends of the upper light guide member 111, and the light sources at both ends of the lower light guide member 121. Different colors can be incident on the lower light guide member 121 from the outer one-color light source 100 and the inner other-color light source 91. For this reason, the upper light guide member 111 and the lower light guide member 121 can have a simple shape, and different colors can be emitted by the upper light guide member 111 and the lower light guide member 121 having a simple structure.

Further, the inner one color light source 90 and the outer other color light source 101, and the outer one color light source 100 and the inner other color light source 91 are turned off when one color is turned on. The mixed color light can be prevented from being emitted from the upper light guide member 111 and the lower light guide member 121.
Further, the light incident on one end of the upper light guide member 111 and the lower light guide member 121 is attenuated toward the other end side. However, according to the configuration of the present invention, the upper light guide member 111 and the lower light guide member 121 are provided in at least two rows, and the upper light guide member 111 and the lower light guide member 121 are disposed close to each other, Since the emitted light colors of the inner one-color light source 90 and the outer one-color light source 100, the inner other-color light source 91, and the outer-other-color light source 101, which are a pair of light sources located diagonally, are the same color, the inner one-color light source 90 located diagonally. The light is attenuated on the other end side of the upper light guide member 111 and the lower light guide member 121 by entering the same color light from the outer one color light source 100, the inner other color light source 91, and the outer other color light source 101. Can be complemented by light of the same color incident from a light source nearby. For this reason, it is possible to emit light well over the entire upper light guide member 111 and the lower light guide member 121.

  When the inner one color light source 90 and the outer other color light source 101, the outer one color light source 100, and the inner other color light source 91, which are light sources of different colors, are provided at both ends of the upper light guide member 111 and the lower light guide member 121, When light of another color incident from one end reaches the outer one-color light source 100 and the inner one-color light source 90 at the other end, the light is reflected by the outer one-color light source 100 and the inner one-color light source 90, and one color is emitted at the other end. Sometimes. However, according to the configuration of the present invention, light of the same color is incident from the inner one-color light source 90 and the outer one-color light source 100, the inner other-color light source 91, and the outer-other-color light source 101 that are located diagonally. Even if one color is emitted from the other end side after being reflected by 100 and the inner one-color light source 90, light emission of one color becomes almost inconspicuous by the light emission of the outer other-color light source 101 and the inner other-color light source 91 adjacent thereto. For this reason, the upper light guide member 111 and the lower light guide member 121 can be made to emit light favorably in other colors.

Furthermore, the direction indicating lamps 62 and 62 are headlamps of the motorcycle 1, and the upper light guide member 111 and the lower light guide member 121 include the curved portions 112b, 114b, 122b, and 124b. 114 b, 122 b, and 124 b easily attenuate light, but the same color light is incident from the inner one-color light source 90 and the outer one-color light source 100, the inner other-color light source 91, and the outer-other color light source 101 located diagonally, and efficiently above The light guide member 111 and the lower light guide member 121 can emit light. For this reason, the visibility of the direction indicating lights 62 and 62 of the motorcycle 1 is good.
Further, a plurality of upper light guide members 111 and lower light guide members 121 are arranged close to each other in the vertical direction, extending obliquely from the center of the vehicle body toward the outside in the vehicle width direction in the front view, and rear in the side view. The inner one-color light source 90 and the outer one-color light source 100, the inner other-color light source 91, and the outer-other-color light source 101, which are inclined upward and are diagonally positioned, are arranged at the center of the vehicle body and on the outer side in the vehicle width direction and the rear upper position. Is done. The upper light guide member 111 and the lower light guide member 121 are positions of the inner one-color light source 90 and the outer one-color light source 100, the inner other-color light source 91, and the outer-other-color light source 101 located diagonally, that is, the vehicle body center and the vehicle width. It emits intense light at a position on the outer side and in the rear upper direction. For this reason, the visibility of the light emission of the upper light guide member 111 and the lower light guide member 121 is good in a wide range in front view and side view.

  Further, since the different colors of the inner one-color light source 90 and the outer other-color light source 101, the outer-one-color light source 100, and the inner-other-color light source 91 are orange and white, the upper light guide member 111 and the lower light guide member 121 are position lamps. And it can function as a direction indicator lamp.

  In addition, according to the first embodiment to which the present invention is applied, the direction indicator lamps 62 and 62 that are vehicle headlamps include an inner one-color light source 90, an outer other-color light source 101, and an outer-one-color light source made of semiconductor elements. 100 and an inner other color light source 91, and an upper light guide member 111 and a lower light guide member 121 for guiding light of a light source incident on an incident portion at one end to the other end. A housing 73 as a rear member is located behind the side light guide member 121, and a recess 86 is provided in a portion of the housing 73 located behind the upper light guide member 111 and the lower light guide member 121. Yes. Thereby, the direction of the light incident on the recess 86 of the housing 73 behind the upper light guide member 111 and the lower light guide member 121 can be changed by the recess 86 so as to be reflected in a direction different from the front. For this reason, it can suppress that sunlight reflects strongly ahead by the housing 73, and the visibility of the direction indicator lights 62 and 62 can be improved.

Further, when the housing 73 is inclined rearward in a side view, sunlight is easily reflected forward, but according to the first embodiment, the reflection toward the front side can be suppressed by the recess 86. For this reason, the visibility of the direction indicating lights 62 and 62 of the motorcycle 1 including the rearward housing 73 can be improved.
Moreover, since the upper light guide member 111 and the lower light guide member 121 are transmission members that transmit light, and the housing 73 is a reflection member that reflects light, sunlight is likely to be strongly reflected by the housing 73. Since the reflection to the front side can be suppressed by the concave portion 86, the visibility of the direction indicator lamps 62, 62 can be improved.
Furthermore, since the lower wall portion of the recess 86 includes a lower reflective surface 86b that is inclined upward in a side view, sunlight can be reflected upward by the lower reflective surface 86b, and the direction indicator lamps 62, The visibility of 62 can be improved.

[Second Embodiment]
Hereinafter, a second embodiment to which the present invention is applied will be described with reference to FIG. In the second embodiment, parts that are configured in the same manner as in the first embodiment are given the same reference numerals, and descriptions thereof are omitted.
The second embodiment is different from the first embodiment in that a recess 186 having a shape different from that of the recess 86 is formed.

14 is a cross-sectional view taken along line XIII-XIII of FIG. 3 in the second embodiment.
The rear member front surface 83 is formed with a recess 186 that is recessed rearward.
The recess 186 is formed in a valley shape that is recessed in a substantially U shape toward the rear side. The recess 186 has an upper reflecting surface 186a that is inclined rearwardly downward and extends rearward from the upper part of the rear member front surface 83, and a lower surface that is inclined rearwardly upward and rearward from the lower part of the rear member front surface 83. A side reflection surface 186b (recessed inclined surface) and a rear reflection surface 186c that vertically connects the rear end of the upper reflection surface 186a and the rear end of the lower reflection surface 186b are provided. The rear reflective surface 186c is a substantially vertical surface that is slightly rearwardly inclined.

  When sunlight S3 is incident on the conventional reflecting surface 283 obliquely from the front upper side, the reflected light R3 is emitted to the front substantially horizontally. For this reason, the reflected light R3 is easy to reach surrounding people and the like, the light emission of the light guide lens 72 itself becomes inconspicuous, and the visibility of the light emission of the light guide lens 72 is lowered.

In the rear member front surface 83 of the second embodiment, when sunlight S4 is incident on the recess 186 obliquely from the front upper side, the sunlight S4 is reflected by the lower reflection surface 186b that is the lower wall portion in the recess 186. The reflected light R4 is reflected in the order of the rear reflective surface 186c and the upper reflective surface 186a, which is the upper wall portion, and is emitted obliquely forward and downward.
For this reason, it is difficult for the reflected light R4 to reach the surrounding people and the like, the light emission of the light guide lens 72 itself can be conspicuous, and the light emission visibility of the light guide lens 72 is good. Here, the sunlight S3 and the sunlight S4 have the same incident angle.

In addition, the said 1st and 2nd embodiment shows the one aspect | mode which applied this invention, Comprising: This invention is not limited to the said embodiment.
In the first and second embodiments described above, a configuration in which the concave portions 86 and 186 are provided in the housing 73 as a rear member provided behind the upper light guide member 111 and the lower light guide member 121 will be described as an example. However, the present invention is not limited to this. The rear member only needs to cover the upper light guide member 111 and the lower light guide member 121 from the rear, and may be, for example, a decorative plate as a design member, an inner member of the front cowl 51, or the like. Moreover, although the back member was demonstrated as a reflective member which reflects light in the said embodiment, this invention is not limited to this. Since the upper light guide member 111 and the lower light guide member 121 can emit a proper amount of light as a direction indicator lamp and a position lamp only by forward light emission from the upper light guide unit 113 and the lower light guide unit 123, The member may not be provided with a silver decorative layer or the like and may be configured not to actively reflect light.
In the first and second embodiments, the upper light guide member 111 and the lower light guide member 121 are arranged in two rows in the vertical direction, but may be a plurality of rows of three or more. .
