PURPOSE:To easily and accurately attain measurement and setting of an angle when measured the angle of a fixed cam piece and when worked such as polishing it. CONSTITUTION:A reference surface 12a is formed partly in an internal peripheral surface in an end 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 reference surface 12a. On the basis of this standardization, the angle may be measured and set. |
