ABSTRACT:
A one-way clutch comprises a plurality of rollers, a retainer having the same number of roller pockets as rollers, a cylindrical shell having the same number of cam grooves as rollers, and springs for normally biasing the rollers toward the cam grooves. The cam grooves are provided at the axially intermediate portion of the shell. The shell is provided at one end with a radially inwardly-turned flange and at the other end with a cylindrical boss portion having a smooth inner surface free of cam grooves. The retainer includes a pair of annular portions at either end and an axially intermediate portion provided with roller pockets. The annular portion which is inserted into the boss portion of the shell has a smooth cylindrical outer surface dimensioned to be pressingly fitted to the boss portion. Thus there are no gaps between the retainer and the shell at the boss portion of the shell, thereby sealing that end of the shell and preventing the outflow of grease and the entry of dust.
