Abstract

The present invention relates to a friction clutch in which the wear in the sliding state can be reduced and an automatic transmission of an automobile using the friction clutch and a non-stage transmission of an automobile and a power distribution device of an automobile and a power transmission device of a motorcycle. That is, according to the present invention, in a configuration of making a pair of clutch members opposite to each other in a radial direction with a plurality of rollers held between them, an angle of a turning axis of each roller relative to the rotation axis of a clutch member is made more than 10° and less than 20°, and in the meantime, the angle of the turning axis of each roller relative to the plane including the rotation axis of the clutch member is made more than 25° and less than 90°, so that a stable frictional force may be generated at all times. In this case, when a load in an axial direction is added to the clutch member, each roller generates sliding friction while turning, and therefore, a wear is extremely smaller than that of a structure of bringing the respective fellow clutch plates into surface contact with each other like a multiple disk clutch.
