PURPOSE:To make the configuration of the entire pointer clear, by arranging a plate member with a window, which is provided at the upper part of a light guiding member, and a light guiding member of the pointer, whose rotary center is made to agree with the center of the plate member, on the upper part of the window. CONSTITUTION:A rotary shaft 7 is inserted in a through hole 9 of a light guiding member 5. A plate member 12 is rotatably attached to the rotary shaft 7. A window 13 is formed in the plate 12. A pointer 3 is made to agree with the rotary center of the plate member and attached on the member 12. A light introducing part 3c is provided on the pointer 3 at the upper part of the window 13. The upper part of the part 3c is coated by a cap 10. The size of the member 12 is determined so that the member 12 is approximately coupled with a light introducing window 11 at the upper surface of the member 5. The lower side of the member 12 other than the window 13 is convered so that it cannot be seen. In this constitution, light to the hole 9 from the outer surface of the member 5 is inputted to the introducing part 3c through a reflecting surface 8 of the hole 9 and the window 13 and goes to the upper part of the pointer 3 through a reflecting surface 3a and the like. Therefore, the part from the rotary center of the pointer 3 to the tip can be lighted. |
