Zusammenfassung:	PROBLEM TO BE SOLVED: To attain miniaturization, lightening of weight, and reducing of torque, while ensuring basic performance of rolling fatigue life, bearing rigidity, etc. SOLUTION: A contact angle α is set to 30 deg or less beyond 18 deg. Ratio LK/b of axial direction length LK of each tapered roller 12, 12 to axial direction length (b) of inner ring elements 17, 17 is set to 0.4 to 0.55. Ratio 2b/H of axial direction length 2b of an inner ring assembly unit 15 to a sectional height H is set to 5.0 or less by exceeding 3.1. Ratio LS/H of an inter-working point distance LS to the sectional height H is set to 4.5 or less beyond 2.6.
