Abstract
A roller bearing unit for a planetary gear is made such that the rollers between the thrust washers are restrained from interference with the thrust washers upon an inclining of the planetary gear either by making the distance between the axially inner faces of washers sufficiently large, or by preventing axial movement of the guide ring between the rollers, so that the axially outer ends are prevented from rubbing hard against the axially inner faces of the washers during running.
