ABSTRACT:
It is possible to eliminate the problem that a conductive part to a light source is subjected to stress by operation of a needle-pointer, thereby improving reliability. A needle-pointer type meter includes: an indicator plate having a first see-through portion and an indicator portion surrounding the first see-through portion; a rotary body having a second see-through portion corresponding to the first see-through portion; a drive device for moving the rotary body; a needle-pointer mounted on the rotary body and moving along the indicator portion around the first see-through portion; light sources illuminating the needle-pointer; and a display device for displaying predetermined information to an observer via the see-through portions. A plurality of light sources are arranged at an interval along the movement route of the needle-pointer. The needle-pointer is made of translucent material which emits light when receiving light from a predetermined light source of the plurality of light sources while moving.
