PROBLEM TO BE SOLVED: To provide a transparent material for a luminous pointer that can prevent a decrease in the amount of light to be distributed laterally when a position of a light source deviates from a predetermined position at a manufacturing stage such as soldering.SOLUTION: A transparent material for a luminous pointer 1 made of a light permeability material guides light emitted from a light source 2 to two or more luminous pointers 3 to allow the two or more luminous pointers 3 to emit light. The transparent material for the luminous pointer 1 comprises a light guiding part 15 for guiding light emitted from the light source 2, a light branching part 16 for forking light guided by the light guiding part 15, and a reflection part 17 for reflecting light branched by the light branching part 16 to the luminous pointer 3. Two areas divided by a line connecting the two or more luminous pointers 3 on top of the transparent material for the luminous pointer 1 is formed to be offset along the line.

    【課題】半田付け等の製造段階で光源の位置が所定の位置からずれても、左右に分配される光量の減少を抑えることができる発光指針用導光体を提供すること。【解決手段】発光指針用導光体1は、光透過性の材料で作成され、光源2から照射される光を2以上の発光指針3に導入して2以上の発光指針3を発光させる。また、発光指針用導光体1は、光源2より照射される光を導入する光導入部15と、光導入部15より導入された光を二股に分岐させる光分岐部16と、光分岐部16で分岐された光を発光指針3へ反射させる反射部17を備え、2以上の発光指針3を結ぶ線により分割される、発光指針用導光体1の上面の2つの領域は、線に沿ってオフセットして形成されることを特徴とする。【選択図】図2
