PROBLEM TO BE SOLVED: To provide a structure of an indicator section which does not lower the degree of freedom of designs and the degree of freedom of light source arrangement even when luminescent colors of multicolor are used. SOLUTION: The structure includes a plurality of light emission sources 1 varying in luminescent colors, and a light receiving section 4 projecting sideways from a light transmission body subject 3 with a one end being an illumination surface and comprises a light transmission body 6 which bends the optical path of the illumination light from each light emission source 1 received by the light receiving section 4 by a reflection surface 5 to emit the illumination light from an illumination surface 2. The reflection surface 5 changes in such a way that its height lowers gradually from the center toward the end. When the photodetecting area of the receiving light is gradually changed along the array direction of the light emission source, the changing degree of the amount of the light can be suitably adjusted.
