PURPOSE:To ensure engagement and prevent rotaion lock of a cage due to biting of a roller in a bearing where the need of alignment for a cage is eliminated by engagement of the cage with the bent plate-like axial end part of an outer ring opening. CONSTITUTION:An opening 3 is provided on the peripheral wall 2 of an outer ring 1, and the axial end part 4 of the opening 3 is formed like a plate bent toward the inside diameter. A cylindrical cage 7 having an opening 8 facing to the opening 3 of the outer ring 1 is disposed in the outer ring 1. The cage 7 has such a trapezoidal section that the axial middle part 7a has a larger diameter than both end parts 7b. The outside diameter of the middle part 7a is made near close to the inside diameter of the outer ring 1, and the cage 7 is guided by the outer ring 1 to provide an outside diameter guide form. A notch 13 for alignment is provided on the marking side end part of the outer ring 1. |
