PROBLEM TO BE SOLVED: To easily assembly rollers, to reduce machining costs, and to improve strength of a cage. SOLUTION: In an example of (a), the rollers 3 of double raw are retained by a machined cage 11, flange portions 5 are formed at both sides of an outer ring 1, and an outer ring guide portion 6 is formed on its central portion. The machined cage 11 has pocket portions in which the rollers 3 can be inserted in a clicked state from a radial inner part. In an example of (b), the rollers 3 of double row are retained by the machined cage 11. Flange portions 8 are formed at both sides of an inner ring 2, and an inner ring guide portion 9 is formed on its central portion. The machined cage 11 has pocket portions in which the rollers 3 can be inserted in a clicked state from a radial outer part. COPYRIGHT: (C)2007,JPO&INPIT
