Claims

[Scope of utility model registration request]

A light guide is fitted into a rotating body that is rotatably supported within a frame and has a display section on its outer periphery, and the light guide is exposed through a light input hole provided on one surface of the frame. In an illumination device for a rotating body, a lamp is disposed above a light input hole on an upper surface, the light from the lamp is inputted from the light input hole into a light guide, and a display section of the rotary body is illuminated with reflected light, The light guide is molded from a resin with high light reflection efficiency, and has first and second standing walls facing each other from the bottom and extending radially. A rotating body, characterized in that it is closed by a third vertical wall forming an inclined surface, and a narrow surface facing the third vertical wall is open, and the open surface faces a display section of the rotating body. Lighting device.
