Abstract
Pillar parts (10) are connected to the inner peripheral surface (5b) of a large-diameter rim part (5) and to the outer peripheral surface (7b) of a small-diameter rim part (7). The inner peripheral surface (5b) of the large-diameter rim part (5) and the outer peripheral surface (7b) of the small-diameter rim part (7) 5 respectively have axial-direction inside portions (5c), (7c) overlapping with the pillar parts (10) in the axial direction and axial-direction outside portions (5d), (7d) not overlapping with the pillar parts (10) in the axial direction. A small-diameter annular member (2) is internally fitted in the axial-direction outside portion (5d) of the inner peripheral 10 surface (5b) of the large-diameter rim part (5). A large-diameter annular member (4) is externally fitted in the axial-direction outside portion (7d) of the outer peripheral surface (7b) of the small-diameter rim part (7).
