<p><P>PROBLEM TO BE SOLVED: To provide a tapered roller bearing in which the seizure of a cage is hard to occur even if the gap between the cage and an outer ring is small. <P>SOLUTION: The cage 5 is so disposed in a rolling element holding space that the inner peripheral surface 5a of itself is positioned on the radial outer side more than the center axis of each tapered roller 4. Oil reserving recesses 6 for reserving a lubricating oil are formed in the outer peripheral surface 5b of the cage in the areas forming column parts 8 formed between the adjacent pocket parts P. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
