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 coverof a pointer movementcontains a rotation driving mechanism including a rotorand an intermediate gear, an output gear, and so on. The rotation driving mechanism transmits rotation based on a measured amount to the output gear, and rotates a pointer bodysupported by a bearing, by way of the output gear. The bearingrotatably supports a shaftof the pointer body. A pointerof the pointer bodyindicates a measuring value according to rotation of the pointer bodyaround the shaft. A light sourceis provided for illuminating the pointerof the pointer body. In the pointer movement, the bearingis formed of a material through which light from the light sourcecan pass, and integrally formed with the lower coverof the containing coverat a position more adjacent to the light sourcethan the shaftof the pointer body, on an optical path.
