This makes it possible to arrange the turn signal light W and the light guide member 80 close to each other in the vehicle width direction while suppressing an increase in the size of the lamp body in the vehicle width direction.

  The upper part of the light guide member 80 is disposed along the outer edge of the winch reflectors 65a and 65b in the vehicle width direction, and is located at a position opposite to the light guide member 80 when viewed from the wink reflectors 65a and 65b. The blinker light sources 133 of the blinker lights W1 and W2 are arranged. Thus, the light guide member 80 is arranged on one side and the turn signal light source 133 is arranged on the other side with the blinker reflectors 65a and 65b interposed therebetween, so that the blinker reflectors 65a and 65b and the light guide member 80 are arranged close to each other. In addition, an increase in the size of the lamp body can be prevented. Further, since the sub-light source light source 123 of the first position light P1 is disposed along the outer edges of the winch reflectors 65a and 65b, by arranging the sub-light source light source 123 at a position on the light guide member 80 side, It becomes easy to make the irradiation light of the sub lamp body light source 123 incident on the light guide member 80.

  Further, a portion of the winch reflectors 65a and 65b protrudes forward of the vehicle body from the light guide member 80 near the light guide member 80. Thereby, in the part of the blinker light W, the blinker light W can be more conspicuous than the first position light P1.

  FIG. 18 is a front view of the light guide member 80. FIG. 19 is a partially enlarged view of the light guide member 80. The light guide member 80 formed of colored transparent or colorless transparent resin or the like receives the irradiation light of the sub-lamp light source 123 from the back side of the incident portion 84 formed at the upper end thereof, and the entire light guide 85. Are configured to emit surface light.

  The light guide member 80 as the first light guide member includes a light guide portion 85 having a large number of linear lens cuts, an upper transmission portion 86 formed along the upper edge of the light guide portion 85, It includes a lower transmission portion 87 formed along the lower edge of the light portion 85, and an outer edge 81 formed along the upper edge of the upper transmission portion 86 and the lower edge of the lower transmission portion 87. An inner mounting portion 82 is formed below the outer edge portion 81 on the inner side in the vehicle width direction and is fixed together with the lower stay 101 of the coloring member 100. An outer mounting portion 83 is formed to be fastened and fixed together with the middle stay 102 of the center 100.

  From the opening 61 of the first extension member 60, only the light guide portion 85, the upper transmission portion 86, and the lower transmission portion 87 are exposed to the front of the vehicle body. Thus, the outline of the light emitting surface of the light guide member 80 can be clearly recognized by the first extension member 60.

  Referring to FIG. 19 in which a portion indicated by a broken line circle A in FIG. 18 is enlarged, a linear lens cut of the light guide 85 is provided on the back surface side of the light guide 85. On the other hand, on the back surface side of the upper transmission portion 86, sub light guide portions 86a, which are linear grooves having a predetermined width T1, are provided at predetermined intervals T2. Accordingly, when the first position light P1 emits light, the entire light guide 85 emits surface light, and the sub light guide 86a of the upper transmission portion 86 emits light linearly.

  Here, when the first position light P <b> 1 is turned off, the light guide portion 85 on which a large number of lens cuts are performed does not have clear coloring, whereas the upper transmitting portion 86 and the lower transmitting portion 87 have the coloring member 100. Can be transmitted through the paint color. Accordingly, even when the first position light P1 does not emit light, such as when the vehicle is parked, the color of the coloring member 100 is visually recognized at the upper transmitting portion 86 and the lower transmitting portion 87, and the outline of the light guide member 80 is formed. Can be emphasized (see FIGS. 20 and 21).

  Further, since the upper transmission portion 86 is formed along the lower contour of the cover member 6 attached to the outer lens 31, the upper transmission portion 86 is located between the cover member 6 and the light guide member 80. As a result, the outline of the cover member 6 can be clearly recognized by the upper transmission portion 86, and the boundary between the first position light P1 and the cover member 6 can be clarified (see FIG. 2).

  Further, since the width T1 of the sub-light guide 86a is smaller than the interval T2 between the sub-light guides 86a, the sub-light guide 86a emits light linearly when the first position light P1 emits light. A novel appearance can be obtained, and at the time of turning off the light, the color member 100 can be seen through from between the sub-light guides 86a, so that the contour of the light guide member 80 can be emphasized.

  At this time, since the upper transmissive portion 86 is located above the light guide portion 85 above the vehicle body, the color by the coloring member 100 is recognized above the light guide portion 85, and the upper transmissive portion 86 is emphasized as an accent of the light guide member 80. It is possible to do. In addition, since the width of the upper transmission section 86 is substantially half the width of the light guide section 85, the difference in appearance is increased by making the areas of the light guide section 85 and the upper transmission section 86 different. The light member 80 can be made to stand out.

  FIG. 20 is a sectional view taken along line XX-XX in FIG. FIG. 21 is a partially enlarged view of FIG.

Above the light source window 71 of the second low beam L2, a main lamp body light source substrate 140 on which a total of six main lamp light sources of the low beams L1 and L2 and the high beam H are mounted is arranged.

  In the first position light P1, the light guide 85 of the first light guide member 80 emits surface light, and the sub light guide 86a emits light in a plurality of lines. On the other hand, even when the first position light P2 is turned off, the coloring member 100 can be seen through between the sub-light guides 86a in the upper transmissive portion 86 of the vertical width T3 and the lower transparent portion 87 of the vertical width T4. The coloring member 100 can be seen through, and the outline of the first light guide member 80 can be emphasized. In the second position light P2, the light guide portion 94 of the second light guide member 90 emits surface light. On the other hand, even if the second position light P2 is turned off, the second coloring member 110 can be seen through the upper and lower transmission portions 93 and 95, so that the outline of the second light guide member 90 can be emphasized. Then, similarly to the upper light transmitting portion 86 and the lower light transmitting portion 87 of the first light guide member 80, the second light guide member 85 has a function of protecting the light guide portion 85 as a reinforcing wall vertically connected to the light guide portion 85. The transmissive portions 93 and 95 of the optical member 90 have a function of protecting the light guide 94 as reinforcing walls extending vertically above and below the light guide 94.

As described above, on the surface of the outer lens 31, the first recess 33 having a shape along the outer shape of the cover member 6 and the second recess 34 in which the bottom surface of the first recess 33 is further recessed are formed. When attaching the cover member 6 to the outer lens 31, the first protrusion 6e of the cover member 6 is inserted into the second concave portion. Accordingly, the cover member 6 can be attached while the first projecting portion 6e is engaged with the second concave portion 34 and positioned, and the cover member 6 is put in the first concave portion 33. It is easy to perform the attaching operation accurately, and it is possible to obtain a high-quality appearance in which the surface of the cover member 6 and the surface of the outer lens 31 are flush with each other. A projection 62a corresponding to the shape of the escape recess 62 is formed on the back surface side of the escape recess 62 corresponding to the second recess 34.

  Further, since the first protrusion 6e and the second concave portion 34 are formed at a position of the outer lens 31 near the center of the vehicle body, when the cover member 6 is attached to the outer lens 31, it is positioned at a position near the center of the vehicle body. , Can be applied outward in the vehicle width direction.

  Further, as shown in FIGS. 5 and 6, the cover member 6 is tapered toward the center of the vehicle body.

I have. Accordingly, as the first protrusion 6e having a curved shape in the vehicle body vertical direction is pushed into the similarly curved second concave portion 34, the first protrusion 6e is guided to the center in the vertical direction. Positioning in the direction becomes easy.

  On the other hand, the cross-sectional shape of the first protrusion 6e in the vehicle width direction is substantially trapezoidal due to the pair of inclined surfaces 6i (see FIG. 6) and the straight portion therebetween. On the other hand, as shown in FIG. 23, the second recess 34 is formed with a second guide surface 34b as an inclined surface for guiding the first protrusion 6e to the center of the second recess 34 in the left-right direction of the vehicle body. . As a result, as the first protrusion 6e having a trapezoidal shape in the lateral direction of the vehicle body is pushed into the second concave portion 34 also having a trapezoidal shape, the first protrusion 6e is guided to the center in the left-right direction. Positioning in the left-right direction becomes easy.

  Further, a third guide surface 33a for guiding the cover member 6 to a predetermined position in the vehicle body vertical direction of the first concave portion 33 is formed at the upper and lower edges of the first concave portion 33. The third guide surface 33a is an inclined surface having a chamfered step between the surface of the outer lens 31 and the bottom of the first concave portion 33. According to the third guide surface 33a, when the entire cover member 6 is attached to the first concave portion 33 while the first projecting portion 6e is accommodated in the second concave portion 34, the outer peripheral portion of the cover member 6 is positioned vertically. And the pasting work becomes easy.

  Furthermore, since the second protrusion 6 g that is in contact with the surface of the first recess 33 is formed on the outer peripheral edge of the adhesive surface side of the cover member 6, the second protrusion 6 g contacts the bottom surface of the first recess 33. Thereby, it is easy to recognize that the pressing work at the time of pasting is sufficient, and the workability can be improved. In addition, the adhesive member 6f is not exposed around the cover member 6, and the appearance of the joined portion can be improved.
