ABSTRACT:
A gauge for a vehicle has a spontaneous light-emission type pointer with a built-in light-emitting device. The pointer is fixed to a pointer shaft rotatably driven in accordance with a measured value. A solid circuit member for supporting a light-emitting device and for coupling the light-emitting device to the pointer shaft is fixed to the pointer. The solid circuit member has a first plated conductive layer for electrically connecting one of the terminals of the light-emitting device to the pointer shaft, and a second plated conductive layer for electrically connecting the other of the terminals to a spring abutment fixed to the pointer shaft in an insulating fashion. The solid circuit member is connected to a power source for lighting the light-emitting device. Consequently, a number of parts required for supplying power to the light-emitting diode can be reduced.
