ABSTRACT:
In order to prevent portions of a thrust rolling bearing from being worn significantly and being burned, grooves are formed on both inner and outer surfaces of a retainer so as to traverse pockets. Lubricating oil is supplied from oiling holes formed in an outer race toward the retainer. The lubricating oil supplied from the oiling holes flows through the grooves to the rolling bearing uniformly.
