<P>PROBLEM TO BE SOLVED: To provide a retainer for a thrust roller bearing excellent in oil permeability and capable of obtaining the thrust roller bearing large in a load capacity. <P>SOLUTION: Many pockets 42 storing rollers 30 are circumferentially formed at equal intervals on an annular retention plate 41 composed of a punching pressed article of a steel plate, a roller stopper member 44 is resin molded so as to surround a part of the side opposite in a circumferential direction of the circumferentially adjacent pockets 42, and a large gap is formed between opposite surfaces to track bases 10 and 20 by integration between the housing track base 10 and the shaft track base 20, thereby improving the oil permeability. <P>COPYRIGHT: (C)2013,JPO&INPIT |
