PROBLEM TO BE SOLVED: To provide a luminous pointer capable of preventing leakage of a light.SOLUTION: A luminous pointer comprises: a translucent member 1 comprising a rotary base part 12 with a light reception part 121 for receiving a light emitted from a light source and a longitudinal indication unit 11 which is illuminated by the light from the light reception part 121; and a cover member 2 comprising a first cover part 21 for covering the surrounding of the rotary base part 12 and having a first opening 211 through which a rear back side of the rotary base part 12 is opened, and a second cover part 22 comprising a see-through window 222 through which a front face of the indication unit 11 is viewed, a pair of side wall parts 223 for covering both side faces of the indication unit 11, and a second opening part 221 for opening a space between these side wall parts 223 to the back face side, and covering the indication unit 11. The cover member 2 comprises a light block rib for blocking the light which leaks to the rear face side of the indication unit 11 out of the light which goes to the indication unit 11 direction from the rotary base part 12 on a position where the first cover part 21 and the second cover part 22 are coupled.SELECTED DRAWING: Figure 2
【課題】光漏れを防いだ発光指針を提供する。【解決手段】光源からの光を受光する受光部121を有する回転基部12と、この受光部121からの光によって光輝する長手状の指示部11とを備えた透光部材1と、回転基部12の周囲を覆うとともに回転基部12の背後側が開口する第1の開口部211を有する第1のカバー部21と、指示部11の前面を視認可能とする透視窓222と指示部11両側面を覆う一対の側壁部223と、これら側壁部223の間を背面側に開口する第2の開口部221とを有し指示部11を覆う長手状の第2のカバー部22と、を有するカバー部材2と、を備えた発光指針において、カバー部材2は、第1のカバー部21と第2のカバー部22とが連結する箇所に、回転基部12から指示部11方向へ進む光のうち、指示部11の背面側へ漏れる光を遮るための遮光リブを有している。【選択図】図2
