PROBLEM TO BE SOLVED: To provide a metal pointer shaft for a meter and driving mechanism of meter pointer which are made with an idea in the shape of a coupling shaft part, to ensure the simplification of a fabrication shape and to form the resin made gear as a coupling object in one body not to relatively move. SOLUTION: A resin-made output stage gear 30 is coaxially coupled in the coupling shaft part 20a of the metal pointer shaft 20 with a boss 30b. In the coupling shaft part 20a, a dent notch 22 is formed in the shaft direction. On the periphery of the coupling shaft part 20a, three grooves 23 are formed in the circumferential direction. The output stage gear 30 is insert-formed with the coupling shaft part 20a of the pointer shaft 20. |
