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 (14)

1. A meter, comprising:

at least one meter unit;

a visor provided around the meter unit and having an upper half and a lower half; 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 such that the light shielding body substantially covers a top portion of the light guiding body so as to expose only an end of the top portion of the light guiding body to emit light, and the light guiding ring is fixed to a mounting part provided in a proximity of an end part of the visor,

wherein cross-sectional shapes of the light guiding body and the light shielding body are different between the upper half and the lower half of the visor, respectively, and

wherein the end of the light guiding body that is exposed by the light shielding body has a cross-sectional flat shape in the upper half of the visor and a cross-sectional slanted shape in the lower half of the visor.

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

3. 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.

4. 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.

5. The meter according to claim 1 , wherein the light guiding ring further surrounds one additional meter unit.

6. The meter according to claim 1 , wherein the light shielding body is coated with a luster.

7. The meter according to claim 3 , wherein there is a space between the diffusing material and the rear part of the light guiding body.

8. The meter according to claim 3 , wherein the diffusing material includes powders of metals.
