Abstract
A needle type gauge includes: a needle that includes a main rotating portion that rotates around a rotation shaft, and an indicator which points out an index part; and an actuator. The main rotating portion includes a light emitting portion that emits strip-shaped light. The light emitting portion is located at the actuator side relative to the indicator, and emits the strip-shaped light to a nearby area to the indicator and located, relative the indicator, at one side in a rotation direction of the indicator. The needle includes a shield which extends in a direction of the actuator from the indicator, extends along the indicator, and blocks, among the strip-shaped light, light directed from the one side in the rotation direction of the indicator to the other side therein.
