    • A lighting structure for a meter device is provided to include a dial, a rotating shaft having a light transmitting property, which is provided in a back surface side of the dial and rotates by receiving a turning force from a motor, a light transmitting pointer which is provided integrally with a light transmitting pointer shaft having a hole formed in a base end part into which an end part of the rotating shaft is inserted and fixed and rotates along a surface of the dial, and a light source which outputs the illuminating lights incident on a base end part of the rotating shaft. The pointer shaft includes a first laterally light-dispersing unit formed with a recessed part recessed toward the light source in an end part over the hole for dispersing a part of the illuminating lights incident on the pointer shaft toward the dial.
    • 仪表装置的照明结构被设置为包括表盘,具有透光性的旋转轴,其设置在表盘的后表面侧并通过接收来自电动机的转动力而旋转;光传输指示器 与具有形成在基端部中的孔的光传输指针轴一体地设置,旋转轴的端部插入并固定在该基端部中,沿着表盘的表面旋转;以及光源,其输出照明灯入射 在旋转轴的基端部上。 指针轴包括:第一横向分光单元,形成有在孔的端部朝向光源凹陷的凹部,用于将入射在指针轴上的一部分照明光朝着表盘分散。
