  7 is a front view of the winker 37, FIG. 8 is a side view, FIG. 9 is a rear view, FIG. 10 is a cross-sectional view taken along the line 10-10 of FIG. As shown in these drawings, the winker 37 has a substantially rhombus shape when viewed from the front, and is formed by superposing a front lens 70 and a base 71 on the back side, and a valve 72 is provided therein. The lens 70 is made of a colored transparent resin, and the base 71 is made of an opaque resin. The lens 70 and the base 71 are engaged with each other at two locations on one side surface by an engagement protrusion 73 on the lens 70 side and an engagement recess 74 on the base 71 side (FIG. 8). It is overlapped with a part of the lower protrusion 71 a provided at the lower portion and fastened with a single bolt 61. The portion where the tightening portion 60 of the lower protrusion 71a does not overlap is exposed.

  As shown in FIG. 10, the lens 70 has a curved surface convex forward, the upper side of the ridge line 75 has an inclined surface that is inclined downward, the lower side of the ridge line 75 is a reverse inclined surface, and is inclined obliquely downward to the rear. A downward slope 76 is formed. The ridge line 75 is provided at a position close to the step wall 62 below the center, and forms a vertex that protrudes most forward in the illustrated cross section. The lower end of the downward slope 76 is located above the upper end portion of the step wall 62, and a space 77 that expands outward is formed between the downward slope 76 and the step wall 62 that is an upward slope.

  An annular wall 78 that protrudes inward and surrounds the bulb 72 is integrally provided on the inner surface of the lens 70 above the ridge 75. The annular wall 78 is fitted in an annular groove 79 provided in the base 71 and sealed with a seal 80 to be waterproof.

As shown in FIG. 11, the peripheral portion of the base 71 overlaps the inside of the downward inclined surface 76 portion of the lens 70 and shields light, so that it is not involved in illumination. Moreover, since the base 71 is colored dark, the downward slope 76 is a dark part.
The position of the fastening portion 60 that protrudes downward substantially vertically from the lower portion of the downward slope 76 is as follows.
It is located in the back of the space 77 formed between the downward slope 76 of the lens 70 and the step wall 62 formed in a reverse inclination. Since the nut portion 81 formed on a part of the lower protrusion 71 a of the base 71 is overlapped inside the tightening portion 60, when the bolt 61 is inserted into the tightening portion 60, the lens 70 is fastened and fixed to the base 71.

  The space 77 expands toward the front, and conversely tapers toward the rear and gradually narrows. The tightening portion 60 is located at the innermost portion, so that the tightening portion 60 is hidden below the downward slope 76. In addition, since the base 71 that overlaps the inside of the downward slope 76 is darkly colored, the downward slope 76 is located in the darkest part by being shaded by the downward slope 76, and is provided in the most inconspicuous position. It is done. Therefore, the bolt 61 provided in this portion is most easily ignored in appearance, and helps to improve the appearance by making it difficult to see the fastening parts.

  As shown in FIG. 9, three mounting projections 82 are formed to protrude outward around the base 71, and as shown in FIG. 12, which is a cross-sectional view taken along line 12-12 of FIG. 7, from the front top cover 31. It is overlaid on the protruding boss 67 and fastened with a tapping screw 83. The fastening structure in the other mounting protrusions 82 is also the same.

As shown in FIGS. 7, 8, and 13, which is a direction indicated by an arrow 13 in FIG. When the bolt 61 is removed, the lens 70 can be easily removed by placing a finger on the notch 84 to improve the maintenance. The notch 84 is an enlarged part (showing a cross section) in FIG. 13, as shown by an imaginary line a, in which the lower end of the downward slope 76 of the lens 70 is notched to reach the lower protrusion 71a. A space corresponding to the thickness of the lens 70 is formed between the notch 84 and the lower protrusion 71a, and a fingertip can be inserted into this space. In FIG. 13, the bolt 61 is omitted, and a through hole 61 a of the bolt 61 is visible in the tightening portion 60.

  FIG. 14 is a front view of the tail lamp unit 90 in a perspective view of the rear portion of the vehicle body. The tail lamp unit 90 is provided between the rear end portion of the rear cover 35 and the rear fender 91, and the side surface is exposed. The tail lamp unit 90 is tapered forward, and a case is constituted by the transparent lens 92 and the coloring base 93. The colored base 93 is colored in a color different from that of the rear cover 35. For example, when the rear cover 35 and the rear fender 91 are blue and the colored base 93 is black, a two-tone color can be produced.

  FIG. 15 is a cross-sectional view taken along the line 15-15 in FIG. 14, in which the transparent lens 92 is convexly curved rearward, and the colored base 93 is fitted inside thereof. The interior is divided into a central taillight portion 94 and left and right blinker portions 95 by a colored base 93. The taillight portion 94 is provided with a tail lamp bulb 97 covered with a red lens 96 at the rear. A winker valve 98 is accommodated and each optical axis is directed rearward.

  In this way, the side effect of the tail lamp unit 90 is exposed, and a two-tone color is produced between the rear cover 35 and the rear fender 91, so that a design effect can be easily achieved.

  Next, the operation of this embodiment will be described. As shown in FIG. 11, a tightening portion 60 that protrudes downward from the lower portion of the winker 37 is provided on the rear end portion of the step wall 62, and a lens tightening bolt 61 is fastened thereto. The fastening portion 60 is also located at the lower end portion (rear end portion) of the downward slope 76 on the ridge line portion 75, and is a space 77 that tapers toward the back formed by the downward slope 76 and the stepped wall 62 that is an upward slope. It is drawn in to the innermost part. For this reason, the tightening part 60 becomes comparatively difficult to see and the appearance can be improved. In addition, since only one lens tightening bolt 61 is required, the mountability and maintainability are also improved.

  In addition, the position of the tightening portion 60 can be made more inconspicuous because the ridge line portion 75 projects outwardly in a bowl shape and is a dark and unobtrusive place behind it. In addition, since the dark color portion is colored on the base 71 itself, which is superimposed on the inner side of the downward slope 76, the fastening portion 60 does not need to be specially painted in dark color, and a dark color structure can be easily realized.

  In addition, since a gap 83 for placing a finger is provided between the lens 70 and the base 71 in the vicinity of the tightening portion 60, the lens 70 can be easily removed to improve maintainability, and the gap 83 is also conspicuous in appearance. Can be eliminated.

The present invention is not limited to the above-described embodiments, and various modifications and applications can be made within the principle of the invention. For example, a target lighting device is not limited to a winker, and a headlight, a taillight, or the like can be used. As for the dark color structure in the tightening portion 60, the downward slope 76 may be directly colored with dark paint or the like. Further, even if such coloring is not performed, the tightening portion can have a dark color structure by making it difficult for light to reach due to a shadow by the ridge line portion 75 or the like.
