せるようになっている。A hollow 3 is formed in the center of rotation 1a in the shape of an inverted triangle, and a slit portion 4 formed at a position corresponding to the upper wall of the hollow 3 has The light diffusion plate 5 is inserted so as to face the inside of the space 3. Then, the light introduced from the back surface into the rotation center portion 1a is
The inclined reflecting walls 3a, 3a of the void 3 are reflected toward the inside of the pointer portion 1b to emit light over the entire length of the surface of the pointer portion 1b.

合がある。However, in such a light emitting pointer, the light diffusing plate 5 allows the light passing through both the reflection walls 3a, 3a in the void 3 to the surface side of the pointer portion 1b. Even if the light is diffused, the light diffusing plate 5 must be adopted as an independent member, which causes an increase in the number of parts.

Leaks to the outside from the narrow gap, and the brightness in the vicinity of the narrow gap increases. For this reason, the luminance is not uniform over the entire surface of the pointer portion 1b, and as a result, there is a problem that the pointer portion 1b does not look good.

Therefore, the brightness over the surface of the pointer portion can be uniformly ensured without increasing in the portion corresponding to the void.
As a result, the appearance of the pointer portion can be kept good. Also ,
Both side walls located near the center of rotation of the pointer are covered with caps, and the colored layer is attached to both side walls of the pointer , so that light that has entered the cap from a void or , When the light directly entering the cap from the back side leaks out from each narrow gap between both side wall portions of the pointer portion and both opposing walls of the cap portion, the light is
It is dimmed by both colored layers. Therefore, it is possible to secure a uniform brightness over the surface of the pointer portion without increasing the brightness in the vicinity of the narrow gap. As a result, it is possible to maintain the appearance of the guidance portion more better.

It will leak out. Therefore, it is possible to secure a uniform brightness over the surface of the pointer portion without increasing the brightness in the vicinity of the narrow gap. As a result, it is possible to maintain the appearance of the guidance portion more better.

ａ、１２ｂが形成されている。The pointer body 10 is provided with a pointer portion 10a made of a light guide material, and the pointer portion 10a is attached to the back surface of the rotation center portion 11 by a cylindrical boss 20 and an annular plate dial 40. It passes through the central hole portion 41 and the central hole portion 51 of the annular light guide plate 50, and is pivotally supported by the rotating shaft 61 of the instrument main body 60. A hollow 12 having an inverted trapezoidal cross section is formed in the center of rotation 11 of the pointer portion 10a so as to open in the width direction of the pointer portion 10a. The two reflecting walls 12 are inclined so as to face the lower side thereof.
a and 12b are formed.
