摘要： A stator is provided with an impeller and a one-way clutch. The stator includes at least one plain bearing and at least one side plate. The plain bearing is arranged adjacent to and on an axially outer side of a side portion of the one-way clutch and between an inner ring and an outer ring of the one-way clutch, and on its inner and outer peripheries, has flanges with bearing tracks formed thereon. The side plate is arranged on an axially outer side of the plain bearing and at a position adjacent to the plain bearing such that the side plate serves not only as a stopper for the plain bearing but also as a bearing track for a needle bearing. The plain bearing and side plate are provided with engageable portions, respectively, and are maintained in engagement with each other via the engageable portions.

摘要： A oneway clutch device comprises a plurality of rollers interposed between an inner race and an outer race to transmit torque only at the time of relative rotation between the inner race and the outer race in one rotational direction, a spring for biasing these rollers toward a direction of engagement, and a retainer having a flange portion to be fitted on the inner race and a plurality of column portions and adapted to retain the rollers and the spring. The spring has a nip portion formed and bent to have a section substantially in a U form for nipping and retaining therebetween one of the column portions of the retainer. There is formed at least one latch means for preventing movement or falling off of the spring.

摘要： A one-way clutch apparatus is provided with a plurality of rollers interposed as torque-transmitting members between an inner ring and an outer ring and a cam surface formed on an outer peripheral wall of said inner ring such that by a combination of the cam surface and the rollers, transmission of rotating force is performed only in one direction between the inner ring and the outer ring. An inner side wall of a flange of a retainer, said flange being arranged alongside the rollers and inner ring, is provided on a radially inner side thereof with an annular recess. An outer peripheral end wall of the annular recess is located on a radially outer side of the cam surface of the inner ring only at deepest parts of the cam surface to permit supply of lube oil to the rollers through the annular recess of the flange and the deepest parts of the cam surface.
