PROBLEM TO BE SOLVED: To provide a double-row tapered roller bearing for improving the durability by effectively circulating grease inside the bearing, while suppressing an increase in the torque due to the agitation resistance of the grease.SOLUTION: In the double-row tapered roller bearing of a rear surface facing type, a rake-up member 11 integrally protruded from the end face of an annular part 7 on the small-diameter side of a cage 5 is provided at the end of a column part 10 of the cage 5, including a pair of rake-up faces 11c formed ranging from an outer-diameter part 11b to an inner-diameter part 11a, as circular faces opposing each other in the rotating direction of the cage 5. The rake-up faces 11c are formed with their front ends bulged beyond the side faces of the column part 10 to pockets 9 in the peripheral direction, respectively. A guide protrusion 12 is protruded from the outer-diameter part 11b of the rake-up member 11 along the outer-diameter face of the column part 10. |
