取付状態が不安定になる問題があった。Therefore, since the pointer shaft 24 is generally made of carbon steel and the boss 22 is made of synthetic resin, the pointer shaft 24 enters the insertion hole 22a of the boss 22. Since the insertion hole is directly press-fitted so as to open the opening 22a, a crack is likely to be formed around the insertion hole near the lower end of the boss 22, and if the crack becomes large, there is a problem that the mounting state of the pointer becomes unstable. It was
