ABSTRACT:
Light projected from a light source is reflected to a pointer side by a reflecting portion in such a state that a dial is rotated to a FOOT position position. Due to this, since light projected from the light source can be emitted to the pointer by bypassing an inside air/outside air changing over switch, the pointer can be illuminated sufficiently without disturbance by the inside air/outside air changing over switch. Moreover, since the reflecting portion is formed by bending partially a predetermined conductor plate58which constitutes a switch circuit, the necessity of a reflector is obviated which would otherwise be necessary exclusively to reflect light projected from the light source to the pointer side. Due to this, since the number of components is reduced, both the production costs and the number of assembling manhours are reduced.
