Slid downward with respect to the guide lamp body 12, the upper engagement protrusion 67 is removed downward from the upper engagement groove 59, and the lower engagement protrusion 69 is removed downward from the lower engagement groove 63, By moving the display body 13 to the front side in the display surface direction, the engagement convex portion 65 of the display body 13 can be removed from the engagement concave portion 58 of the guide light main body 12, and the display body 13 can be detached from the guide light main body 12. .

  When the display body 13 is slid downward with respect to the guide light body 12, the display body 13 is moved to the near side in the display surface direction and slid downward beyond the position where it can be removed from the guide light body 12. Since the protrusion 68 engages with the catching groove 60, the display body 13 can be prevented from dropping. Even when the catching protrusion 68 is engaged with the catching groove 60, if the display body 13 is moved to the front side in the display surface direction, the catching protrusion 68 is engaged through the inclined surface 62 on the front side of the catching groove 60. The display body 13 can be easily removed from the recess 58, and the display body 13 can be easily removed.

  Thus, the light source unit 23 is provided on the upper part of the guide lamp body 12, the display body 13 is attached to the guide lamp body 12 by being attached to the guide lamp body 12 and sliding upward after the attachment, and the display body 13 is attached. Since the guide light body 12 is detached from the guide light body 12 by sliding downward and moving to the near side after the slide, the display body 13 can be easily attached and detached, and displayed on the light source section 23. The upper portion of the light guide plate 43 of the body 13 can be pressed, the positional relationship between the light source unit 23 and the display body 13 can be stabilized, and variations in luminance of the display body 13 can be reduced.

  In particular, since the light source holder 83 attached to the guide lamp body 12 via the support portion 91 is given elasticity in a direction facing the light guide plate 43 via the support portion 91, the light source holder is attached when the display body 13 is attached. The light guide plate 43 can be attached to the light guide plate 83, the positional relationship between the light emitting diode 81 and the light guide plate 43 is kept constant, the variation in the amount of light incident on the light guide plate 43 is reduced, and the brightness of the display 13 Can be made constant.

  Further, since the incident surface of the light guide plate 43 contacts the light source holder 83, a certain distance can be secured between the light emitting diode 81 and the incident surface of the light guide plate 43 via the light source holder 83, and the light guide plate 43 enters the light guide plate 43. The variation in the amount of incident light can be reduced, the luminance of the display body 13 can be made constant, and the light guide plate 43 does not hit the light emitting diode 81, so that the light emitting diode 81 can be prevented from being damaged.

  In addition, since the light source holder 83 has a substantially U-shaped cross section and the light guide plate 43 is inserted into the groove, the inner surface of the groove of the light source holder 83 functions as a reflecting surface, and efficiently guides the light from the light emitting diode 81. The light can be incident on the light plate 43.

  In addition, the light source unit 23 is attached to the guide light body 12, and the display body 13 can be attached to and detached from the guide light body 12 to which the light source unit 23 is attached. Wiring with the lighting unit 28 can be completed on the guide lamp main body 12 side, and when the display body 13 is attached or detached, it is not necessary to attach or detach the light source 23, and the display body 13 can be easily attached or detached.

  In addition, since the light source cover portion 45 that covers the light source portion 23 of the guide lamp main body 12 is integrally provided on the upper portion of the cover body 41 of the display body 13, no gap is formed on the surface of the display body 13, and the appearance can be improved.

  Furthermore, since the upper part of the display board 42 is inserted into the back side of the light source cover 45 of the cover body 41 from below and the lower side of the display board 42 is fitted and attached to the cover body 41, the display board 42 is scratched during assembly. The appearance can be improved.

  Further, since the overlapping portion 46 at the bottom of the display body 13 overlaps the lower surface of the guide light main body 12, the generation of a gap can be prevented and the appearance can be improved. In addition, the overlapping portion 46 at the bottom of the display body 13 overlaps and is joined to the lower surface of the guide lamp body 12, thereby functioning as a stopper for sliding upward of the display body 13 and leading to the light emitting diode 81 of the light source section 23. The accuracy of the distance to the light plate 43 can be obtained.

  In addition, the reinforcing plate 101 disposed in the guide lamp main body 12 functions as a heat radiating plate for suppressing the heat generation of the light emitting diode 81, and a decrease in light output due to the temperature characteristics of the light emitting diode 81 can be minimized. Since the light source holder 83 is first attached to the guide lamp main body 12 and covered with the display body 13, it is difficult to adopt a heat dissipation structure later, but by disposing this heat sink in the guide light main body 12, the heat dissipation structure can be improved. Can be easily adopted. By forming the heat sink in a substantially L shape, it is possible to prevent interference with other parts arranged in the guide light main body 12.

  In addition, a guide light is applicable not only to a double-sided display type but to a single-sided display type.
