SOLUTION: A 1st recessing part 95 of a rectangular recessing part is formed with pressing on a 1st face 87 of a carrier 71. A circular shape 2nd recessing part 96 is formed by milling on a 2nd face 88. The 2nd recessing part 96 is made to reach the bottom of the 1st recessing part 95, and an attaching hole 100 is composed of two recessing parts 95, 96. A part of the outer circumference of the top end of a shaft 70 is cut and it is made in a half circular cross-section shape and a flat face 90 is formed.
