Meter

1. A meter comprising:

a meter unit;

a visor arranged around the meter unit;

a wiring board;

a light source mounted on the wiring board;

an annular light guiding member provided within the visor at a side of a light emitting surface of the light source so as to surround the meter unit, wherein the light guiding member is formed to protrude to the front in a longitudinal direction of the meter from a vicinity of the light source; and

a light emitting portion forwardly emitting light emitted by the light source and transmitted through the light guiding member and annularly provided along an edge portion of the visor so as to surround the meter unit,

wherein a protruding-length of the light guiding member varies with arrangement positions in the light guiding member.

2. The meter according to claim 1 , wherein a light-source-side surface of the light guiding member has a portion which corresponds to the light source, formed substantially flat.

3. The meter according to claim 2 , wherein a light-emitting-side surface of the light guiding member that is opposed to the light-source-side surface, is continuously formed and varies in length in the longitudinal direction along a circumferential direction of the meter unit.

4. The meter according to claim 1 , wherein the meter includes a plurality of irradiating-light-sources irradiating the meter unit and a plurality of emitting-light-sources for causing the light emitting portion to emit light, and the light guiding member is provided at a side of a light emitting surface of each of the emitting-light-sources.

5. The meter according to claim 1 , wherein at least a portion of the light guiding member is disposed entirely within the visor in the longitudinal direction.

6. The meter according to claim 5 , wherein the light source is disposed within the visor.

7. The meter according to claim 1 , wherein the visor extends further in the longitudinal direction of the meter than the light guiding member.
