Abstract
A thrust roller bearingis provided in which one half of total gap which results from adding up an outer diameter side in-bearing gapand an inner diameter side in-bearing gapin diametrical direction is made larger than the amount of eccentricity between a memberwhich supports an outer ringand a memberwhich supports an inner ring. When inside diameter at distal end of an outer locking portionalong a distal edge portion of an outer flangeis φD, outside diameter of a cageis φD, outside diameter at a distal end of an inner locking portionalong a distal edge portion of an inner flangeis φD, inside diameter of the cageis φDand thickness of the cageis t, A, B are defined as A=(D−D)/t and B=(D−D)/t, 0.1≦A, B≦5 is satisfied.
