A bearing 15 composed of 4 is rotatably attached. A press-fitting portion 17 is formed on the inner end side of the large diameter portion 12 via a positioning step portion 16, and an inner side plate 18 is press-fitted into the press-fitting portion 17. The side plate 18 has a diameter slightly smaller than that of the outer ring 14 and is pressed against the positioning step portion 16.
