<p>An indicator which is useful as a speedometer of a car. A driving internal device (2) is fitted to a printed circuit board (1), and a rotary shaft (6) comprising a hollow shaft is supported by shaft support portions (4, 5) of this driving internal device (2). A pointer (9) is fitted to this rotary shaft (6) and is rotated by the driving internal device (2) through the rotary shaft (6). A light emission diode (12) is disposed inside the rotary shaft (6) and is fixed to the printed circuit board (1). Rays of light of the light emission diode (12) are received by a light reception surface (9a) of the pointer (9) and are then reflected by a reflection surface (9b), so that the pointer (9) emits the rays of light.</p> |
