Abstract

Provided is a pointer illumination structure which is simple, and in which a rotary part including a pointer body can be made lightweight. A containing cover 20 of a pointer movement 1 contains a rotation driving mechanism including a rotor 32 and an intermediate gear 33, an output gear 34, and so on. The rotation driving mechanism transmits rotation based on a measured amount to the output gear 34, and rotates a pointer body 10 supported by a bearing 22c, by way of the output gear 34. The bearing 22c rotatably supports a shaft 11 of the pointer body 10. A pointer 12 of the pointer body 10 indicates a measuring value according to rotation of the pointer body 10 around the shaft 11. A light source 13 is provided for illuminating the pointer 12 of the pointer body 10. In the pointer movement 1, the bearing 22c is formed of a material through which light from the light source 13 can pass, and integrally formed with the lower cover 22 of the containing cover 20 at a position more adjacent to the light source 13 than the shaft 11 of the pointer body 10, on an optical path.
