PROBLEM TO BE SOLVED: To provide a retainer for a needle bearing and a needle bearing capable of inhibiting abrasion of an end surface while being lightweight and relatively inexpensive. SOLUTION: Since a resin part 12A is made of a resin, lightweight of the needle bearing 10 is totally accomplished and low cost can be accomplished. The abrasion can be inhibited by a metal material 12c provided on an annular part even if an axial end surface of the needle bearing 10 interferes with other parts. COPYRIGHT: (C)2004,JPO
