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 roller type one-way clutch includes an outer race in which at least one pocket having a cam surface on an inner periphery thereof is formed, an inner race which is spaced away from the outer race on an inside diameter side in a radial direction and which is relatively rotatably disposed concentrically with respect to the outer race, a roller which is disposed in the pocket and which engages with the cam surface to transmit a torque between the outer race and the inner race, a spring which is disposed between the outer race and the roller in the pocket and which urges the roller in a direction in which the roller engages with the cam surface, and a side plate secured to be in contact with one end surface in an axial direction of the outer race. The side plate has a non-circular shape, the one end surface in the axial direction is annular, and at least a portion of the one end surface in the axial direction of the outer race is exposed in a state in which the side plate is secured.
