To realize a structure which can prevent occurrence of rust between base end parts of a pair of stationery flange pieces of an outer ring which are located in proximity with each other in a circumferential direction.SOLUTION: Between base end parts of a pair of stationery flange pieces 10a, 10b which are located in proximity with each other in a circumferential direction, a projection part 18, which projects to radial direction outward from an outer peripheral surface of an outer ring 6a, and of which a radial direction outward projection quantity becomes larger at a circumferential direction intermediate portion with respect to circumferential direction both side parts, is provided. An outer peripheral surface of the projection part 18 are smoothly connected to a convex circular surface 21 of the circumferential direction intermediate portion and a concave circular surface 22 of the circumferential direction both side parts.SELECTED DRAWING: Figure 2

    【課題】外輪のうちで、円周方向に互いに近接配置された1対の静止フランジ片の基端部同士の間に、錆が発生することを防止できる構造を実現する。【解決手段】円周方向に互いに近接配置された1対の静止フランジ片10a、10bの基端部同士の間に、外輪本体6aの外周面から径方向外方に突出し、かつ、径方向外方への突出量が周方向両側部よりも周方向中間部で大きくなった突起部18を設ける。突起部18の外周面を、円周方向中間部の凸円弧面21と円周方向両側部の凹円弧面22とを、それぞれ滑らかにつないで構成する。【選択図】図2
