<P>PROBLEM TO BE SOLVED: To prevent that a light from a light source of an instrument inside is exposed from an opening of a dial plate and also to increase integrality of a pointer and the dial plate. <P>SOLUTION: The pointer instrument 1 is configured in such a manner that a circular annular pointer cap portion 5 at a base side of a light guiding pointer 4 is arranged in the opening 3 of the dial plate 2, an annular light-shielding ring 6 is disposed over the rear side of the pointer cap portion from a rear face of the dial plate, and a light shielding ring includes a collar part 12 having the large diameter in contact with the rear face 2a and a cylindrical part 16 having the diameter smaller than that of the pointer cap portion while being located at the rear side, and inside of the cylinder part having the smaller diameter, a light guiding base part 23b of the pointer is located. Also a pointer instrument 41 is configured in such a manner that a diaphragmatic recess part 43 is formed on the dial plate 42, and the circular annular pointer cap part 5 at the base side of the light guiding pointer 4 is arranged in the diaphragmatic recess part, and the diaphragmatic recess part is composed of an annular wall 49 continued with curvature from a flat plate part 48 of the dial plate and a collar wall 50 continued with curvature to inner direction from the annular wall. <P>COPYRIGHT: (C)2012,JPO&INPIT |
