PROBLEM TO BE SOLVED: To provide a conical roller bearing device capable of reducing rotational torque by agitating resistance, by making lubricating oil flow in by straightening and restricting the lubricating oil. SOLUTION: This conical roller bearing device has a plurality of conical rollers interposed between an inner race 1 and an outer race 2, and is used under a condition of making oil flow in from a small end side opening part of the inner race 1. An oil straightening member 6 having an inner diameter substantially equal to an opening circle diameter of the outer race 2 and axially extending, is arranged in an end part on the opening part E side of the outer race 2. The oil straightening member 6 may be integrally formed with the outer race 2. COPYRIGHT: (C)2006,JPO&NCIPI
