問題点がある。In such a configuration, when adjusting the screw fitting position of the turning angle adjusting stopper bolt 6, as shown in FIG. 10, the turning angle adjusting stopper bolt 6 is fixed at the adjusted screw fitting position. It is necessary to pass the tip of a tool 15 such as an eyeglass wrench for loosening or tightening the nut 14 to be passed through a narrow gap between the head of the turning angle adjustment stopper bolt 6 and the outer peripheral surface of the boss 1A. Inevitably, the tip of the tool 15 such as an eyeglass wrench inevitably interferes with the outer peripheral surface of the boss 1A, which makes it difficult to use the tool 15 such as an eyeglass wrench. However, there is a problem that the screw fitting position cannot be adjusted and the turning angle cannot be adjusted.
