PURPOSE:To easily and accurately attain measurement and setting of an angle at the time of measuring the angle of a fixed cam piece and at the time of working such as polishing it. CONSTITUTION:A diameter directional slit part 12 is formed in an end face part of a cylindrical shaft main unit 11. Accordingly, an angle about an axis O of the shaft main unit 11 can be standardized by the slit part 12. Based on this standardization, the angle may be measured and set. |
