Abstract: 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.

Abstract: The present invention provides a one-way clutch comprising sprags disposed between outer and inner races which are rotated relative to each other and adapted to transmit torque, spring members for biasing the sprags toward an engagement direction, and a cage which has a plurality of window portions for holding the sprags and in which a column portion between the adjacent window portions is partially cut at a predetermined position to connect between the adjacent window portions and the column portion is bent to form an elastic piece elastically engaging with the outer race or the inner race, and wherein a recessed portion is provided in a side surface of a bent portion of the elastic piece in a bent direction.

Abstract: There is provided a method for producing a friction plate, capable of improving the throughput of friction material and reducing the time and work required for adhering friction material segments to a core plate. The method produces a friction plate having oil grooves communicating between the internal periphery and the external periphery, by fixing friction material segments formed from a friction material to a core plate, and is featured by forming the oil grooves by plastic working of the friction material and fixation of the friction material segments with predetermined gaps therebetween to the core plate.
