Abstract
Construction of a thrust roller bearing with races is achieved in which a function of preventing a cage, first thrust raceand second thrust racefrom separating from each other can be maintained, the amount of eccentricity that is allowed between a pair of members that rotate relative to each other can be increased, and the amount of lubricant that can flow inside the bearing can be increased. The outer diameter of the outer-diameter side flangethat is formed around the outer circumferential edge section of the first thrust raceis 60 mm to 120 mm, the inner diameter of the inner-diameter side flangethat is formed around the inner-circumferential edge section of the inner-diameter side flangeis 40 mm to 80 mm, and the internal gap is 1 mm to 2 mm. Therefore, outer-diameter side locking sectionsare intermittently formed in the circumferential direction on the tip-end edge of the outer-diameter side flange
