<P>PROBLEM TO BE SOLVED: To further increase a load sustainable by a conical roller bearing without increasing an outer diameter of the conical roller bearing. <P>SOLUTION: The conical roller bearing includes an outer ring 11, an inner ring 20 disposed on the inner peripheral side of the outer ring 11, a conical roller 40 rolling between the outer ring 11 and the inner ring 20, and a holder 30 for arranging a plurality of conical rollers 40 with spaces in a circumferential direction. A guide flange 23 projected in a diameter direction is formed in one of the small-diameter side of the outer ring 11 and the small-diameter side of the inner ring 20. The holder 30 is located between the guide flange 23 and the conical roller 40. A first slide contact surface 31 is formed in the holder 30 in a rotational direction with respect to the guide flange 23. A second slide contact surface 32 is formed in the holder 30 in a rotational direction with respect to the conical roller 40. An engaging part 33 is formed in the holder 30 to be engaged with the conical rollers 40 in the circumferential direction, and holds the conical rollers 40 with spaces in the circumferential direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
