## Abstract

A meter includes at least one meter unit, a visor provided around the meter unit; and a light-emitting part. The light-emitting part includes a light-guiding ring, a light source and a prism provided between the light guiding ring and the light source. The light-emitting part is annularly provided so as to cover an outer periphery of a dial panel of the meter unit. The light guiding ring is composed of a light guiding body and a light shielding body. The light shielding body is integrally formed with the light guiding body so as to cover the light guiding body. The light guiding ring is fixed to a mounting part provided in a proximity of an end part of the visor.

## Claims

### Claim 1

A meter, comprising:
at least one meter unit;
a visor provided around the meter unit; and
a light-emitting part including a light-guiding ring, a light source and a prism provided between the light guiding ring and the light source, the light-emitting part being annularly provided so as to cover an outer periphery of a dial panel of the meter unit;
wherein the light guiding ring is composed of a light guiding body and a light shielding body, the light shielding body is integrally formed with the light guiding body so as to cover the light guiding body, and the light guiding ring is fixed to a mounting part provided in a proximity of an end part of the visor.

### Claim 2 (depends on 1)

The meter according to claim 1, wherein the light guiding body is formed so as to be progressively or incrementally narrower toward an end of the light guiding body, and the end of the light guiding body is provided so be projected from the light shielding body.

### Claim 3 (depends on 1)

The meter according to claim 1, wherein the light guiding ring includes a diffusing material provided in a rear part of the light guiding body.

### Claim 4 (depends on 1)

The meter according to claim 1, wherein the prism is provided inside a leg formed in the visor, and the prism is provided so that there is space between the prism and the light guiding ring.
