ABSTRACT:
The pointer illuminator includes: an optically transparent pointer member having a reflecting surface for a pointer, which surface reflects, light incident on a predetermined surface of incidence and guides the light to a tip of the pointer; a light source arranged around a drive shaft of the pointer member; and an optically transparent light-guiding member, which guides light from the light source to the surface of incidence and includes a first light-guiding reflecting surface provided on a face of the light-guiding member, an angle which the face forms with a center axis of the light source becoming smaller as the face leaves the light source so that the first light-guiding reflecting surface reflects the light from the light source to convert the light into approximately parallel light rays, whereby the light-guiding member guides the parallel light rays to the surface of incidence.
