Abstract
A structure of a scale graduation includes: a meter dial plate, a light-guiding body made of a translucent material in a dark color, a three-dimensional graduation disposed in a protruding manner on a front surface of the light-guiding body and made of a translucent material in the dark color disposed on the front side of the meter dial plate, and a light source that makes light enter the three-dimensional graduation through the light-guiding body. When the light source emits outgoing light, the three-dimensional graduation lights on in a light color different from the dark color.

A structure of a scale graduation comprising:
- a meter dial plate;
- a light-guiding body made of a translucent material in a dark color;
- a three-dimensionally designed portion disposed in a protruding manner on a front surface of the light-guiding body, and made of the translucent material in the dark color disposed on the front side of the meter dial plate;
- and
- a light source that makes light enter the three-dimensionally designed portion through the light-guiding body, wherein
- when the light source emits outgoing light, the three-dimensionally designed portion lights on in a light color different from the dark color,
- a grained surface is provided on a place in the light-guiding body where light enters from the light source, and corresponding to the three-dimensionally designed portion, and
- the place in which the grained surface is provided is on a side of the light-guiding body that is away from the front surface of the light-guiding body.

- and
- a light source that makes light enter the three-dimensionally designed portion through the light-guiding body, wherein
- when the light source emits outgoing light, the three-dimensionally designed portion lights on in a light color different from the dark color,
- a grained surface is provided on a place in the light-guiding body where light enters from the light source, and corresponding to the three-dimensionally designed portion, and
- the grained surface is configured to diffuse the light from the light source such that the light is thereafter emitted from the three-dimensionally designed portion, and further configured to reflect light that enters the three-dimensionally designed portion such that the light reflected is emitted from the three-dimensionally designed portion.
