PROBLEM TO BE SOLVED: To provide a luminous pointer capable of suppressing light emission unevenness of a pointer body.SOLUTION: A luminous pointer comprises: a pointer body 10 which has light transmissivity and comprises a rotation center area R and an indication unit 12 for indicating a measurement value display part; and a pedestal member 30 having a light guide part 62 for guiding illumination light to the pointer body 10 so that the pointer body 10 emits light. A cover member 20 which has no light transmissivity for covering the pointer body 10, the light guide part 62 and a shielding member 70 comprises a slit 21a for exposing a front face of the pointer body 10. The pedestal member 30 comprises a light amount adjustment part 75 for adjusting a light amount of the illumination light to be introduced to the rotation center area R so that illumination balance between the rotation center area R and the indication unit 12 is maintained.
【課題】 指針本体の発光ムラを抑制することが可能な発光指針を提供する。【解決手段】 回転中心領域Rと計測値表示部を指示する指示部12とを有する透光性の指針本体10と、この指針本体10が発光するように照明光を指針本体10に導くための導光部62を有する台座部材30とを備え、指針本体10と導光部62と遮蔽部材70とを覆う非透光性のカバー部材20には、指針本体10の前面を露出させるスリット21aが設けられている発光指針において、台座部材30には、回転中心領域Rと指示部12との照明バランスが保たれるように、回転中心領域Rに導入される照明光の光量を調整する光量調整部75が設けられている。【選択図】図1
