    • 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.

    • The meter has a back light illuminating with a predetermined color, a display portion disposed in font of the back light and being changeable between a positive mode and a negative mode at a predetermined state, and a reverse control device determining whether an engine of a vehicle is in an initial starting step or the vehicle is in a running state. The control device reverses the display portion in response to a result of the determination. The control device changes the display portion from one of the positive and negative modes to the other at a lower speed when the control device determines that the vehicle engine is in an initial starting step than when the control device determines that the vehicle is in a running state. When the control device determines that the vehicle engine is in an initial starting step, the control device changes the display portion in one of the positive and negative modes from a neutral contrast state.
