PROBLEM TO BE SOLVED: To provide a double row bearing capable of suppressing axial movement of a rolling element and a cage, to suppress degradation of durability.SOLUTION: A double row bearing includes an outer ring 3 having a first outer raceway surface 3a and a second outer raceway surface 3b on an inner peripheral face, a shaft 2 having a first inner raceway surface 2a and a second inner raceway surface 2b on an outer peripheral face, a plurality of balls 41 disposed between the first outer raceway surface 3a and the first inner raceway surface 2a, a plurality of rollers 42 disposed between the second outer ring raceway surface 3b and the second inner ring raceway surface 2b, a holding member 5 having a ball cage 6 rollably holding the plurality of balls 41, and a roller cage 7 for rollably holding the plurality of rollers 42, and a second seal member 82 axially opposed to the roller cage 7. In the holding member 5, the axial movement to the second seal member 82, of the roller cage 7 is restricted by connecting the ball cage 6 and the roller cage 7. |
