<P>PROBLEM TO BE SOLVED: To provide a thrust needle bearing performing rotation stop by abutting a thrust race on a counter member such as a housing, the bearing which suppresses wear of the counter member even if the thrust race repeatedly abuts on the counter member. <P>SOLUTION: A plurality of protrusions 8 protruding outside in a radial direction are formed in the race portion 5 of the thrust race 4. The protrusion 8 comprises: a protruded part 9 on the same plane as the race portion 5 formed by a press forming; and a flange portion 10 formed by bending both ends in the peripheral direction being a breaking surface by the press forming of the protruded part 9, onto the inner cylinder 6 side in the axial direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
