    • 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.

    • A pointer device (1) has a light-guiding body (10), constituted by a shaft (11), a hub (17) coaxial with the shaft (11) and having a rear surface (19) covered by a shield (20), and a pointer (28), which projects radially from the hub (17); the device (1) also has a cap (32), which is defined by at least one piece separate from said light-guiding body (10) and is mounted on the hub (17) in a fixed position; the hub (17) has an emitting surface (25b), a first reflecting surface (39) configured to reflect and direct a first light flow from the shaft (11) to the pointer (28), and at least a second reflecting surface (41a, 41b), which is configured to reflect and direct a second light flow from the shaft (11) to the emitting surface (25b) and is, at least in part, set apart from the first reflecting surface (39); the cap (32) has at least one light-permeable area (33), aligned with the emitting surface (25b), and a barrier (44) arranged radially between the emitting surface (25b) and the first reflecting surface (39).
    • 一种指针装置(1)具有由轴(11)构成的导光体(10),与该轴(11)同轴并具有由护罩(20)覆盖的后表面(19)的轮毂(17) )和一个从轮毂(17)径向伸出的指针(28); 所述装置(1)还具有帽(32),所述帽由与所述光导体(10)分离的至少一个部件限定并且在固定位置安装在所述毂(17)上; (17)具有发射表面(25b),被配置为将来自轴(11)的第一光流反射并引导至指针(28)的第一反射表面(39),以及至少第二反射表面( 其被配置为将来自所述轴(11)的第二光流反射并引导至所述发射表面(25b)并且至少部分地与所述第一反射表面(39)分开设置; (32)具有与发射表面(25b)对准的至少一个透光区域(33)以及径向地布置在发射表面(25b)与第一反射表面(39)之间的屏障(44)。
