The present invention is a tapered roller bearing that, by using a cage (140) that is guided in the radial direction by the inner circumference of an outer race (110) and by providing a flange (147), which projects toward an inner race (120), on a second circular section (142) on the large diameter side of the cage (140), prevents strong contact between the posts (144) of a cage (140) and tapered rollers (130) due to centrifugal force, improves the inflow of lubricating oil into the interior of the bearing, and facilitates the distribution of said influent lubricating oil to the posts (144) and guided surfaces (145, 146) of the cage (140) to prevent abnormal wear of the posts (144). |
