Abstract:
Disclosed is a pointer-type meter with good uniformity of illumination of a display section even when there are few light sources, and with little or no displacement of each member when positioning is performed. A circuit board provided in the pointer-type meter comprises a first light-emitting element (332a) that emits light in a direction towards a first rotary shaft (3110). The pointer-type meter comprises: a first reflecting unit (321) positioned between the circuit board and a display plate (31) and that surrounds part of the circumference of the rotary shaft (3110) and reflects light towards the outer edge of a speed display unit (311); and a second reflecting unit (322) positioned between the circuit board and the display plate (31) and that reflects the light reflected by the first reflecting unit (321) to illuminate the speed display unit (311).
