PROBLEM TO BE SOLVED: To increase the number of stored rollers without reducing rigidity of a holder and suppress increase of dragging torque as much as possible. SOLUTION: In this tapered roller bearing 1 provided with an inner ring 2, an outer ring 3, a plurality of tapered rollers 4 arranged between the inner ring 2 and the outer ring 3 so as to roll freely, and the holder 5 for holding the tapered rollers at a predetermined interval on the circumference, outside diameter of the holder 5 is set to such dimension that it does not come into contact with the outer ring 3 in a neutral condition and comes into contact with the outer ring 3 when moving in the radial direction.
