<P>PROBLEM TO BE SOLVED: To provide a double-row rolling bearing in which both first and second inner rings are connected to each other and held by a simple structure. <P>SOLUTION: An inner ring 30 is divided into two parts: the first inner ring 31 and the second inner ring 41. An annular recess 35 and an annular projection 45 fitted to each other are formed in and on the end surfaces of both the first and second inner rings 31, 41 opposed to each other. A first annular groove 36 is formed in the inner peripheral surface of the annular recess 35. A second annular groove 46 aligned with the first annular groove when the annular recess 35 is fitted to the annular projection 45 to a predetermined fitting position. A snapring 50 is interposed between both the first and second annular grooves 36, 46, both the first and second inner rings 31, 41 are connected to each other and held. <P>COPYRIGHT: (C)2008,JPO&INPIT |
