PROBLEM TO BE SOLVED: To provide a pointer illuminator capable of suppressing leakage of light from a gap between a pointer body and a dial plate.SOLUTION: A pointer illuminator 10 includes: a case 11 for supporting a dial plate 13; a rotary shaft member 21 which passes through the dial plate 13 and is rotatable; a cylindrical light guide body 32 which surrounds the rotary shaft member 21; a light source 31 which is provided on a lower surface side of the light guide body 32 so as to supply light to the light guide body 32; a translucent pointer body 33 which is supported on an upper side of the rotary shaft member 21 and has a light receiving surface for receiving light from an upper end face of the light guide body 32; an outside light shielding wall 23w which is supported by the pointer body 33 and extends toward the light guide body side; an inside light shielding wall 41 which is supported by the case 11 and cylindrically extends toward the pointer body side inside the outside light shielding wall 23w; and a flange section 42 which is provided on a radial direction outer face of the inside light shielding wall 41. The flange section 42 is located on a top face of the dial plate 13, and at least a partial region on the top face of the flange section 42 has a reflection section for reflecting light from an upper side inward.SELECTED DRAWING: Figure 2

    【課題】指針本体と文字板との間隙から光漏れを抑制できる指針照明装置を提供する。【解決手段】指針照明装置10は、文字板13を支持するケース11と、文字板13を貫通して回転可能な回転軸部材21と、回転軸部材21を取り囲む筒状の導光体32と、導光体32の下面側に設けられ導光体32に光を供給する光源31と、回転軸部材21の上方側に支持され導光体32の上端面からの光を受容する光受容面を有する透光性の指針本体33と、指針本体33に支持され導光体側に向けて筒状に延在する外側遮光壁23wと、ケース11に支持され外側遮光壁23wの内側において指針本体側に向けて筒状に延在する内側遮光壁41と、内側遮光壁41の径方向外面上に設けられたフランジ部42とを備え、フランジ部42は、文字板13の上面上に位置し、フランジ部42の上面の少なくとも一部の領域は、上方側からの光を内方側へ反射させる反射部を有する。【選択図】図2
