A rolling-contact bearing type clutch which comprises an inner ring having an inner raceway surface of a mono-hyperboloid of revolution; an outer ring having an outer raceway surface of a mono-hyperboloid of revolution; rollers disposed in between the inner and outer rings with their center axes slanted, and with the surface of each roller being in line contact with the inner and outer raceway surfaces; and energizing devices energizing either the inner ring or the outer ring in the axis line direction to narrow the gap of the raceways; and annular members provided on the inner and outer rings so as to bring possible axial movements of the rollers to a stop.

A rolling-contact bearing type clutch comprising an inner rotation body, an outer rotation body, a plurality of intermediate rotation bodies, and energizing means; said inner rotation body having an inner raceway surface of a mono-hyperboloid of revolution about one axis line; said outer rotation body having an outer raceway surface of a mono-hyperboloid of revolution about said axis line; said inner and outer raceway surfaces facing each other to form a combination of raceways; said intermediate rotation bodies each having a cylindrical rolling surface and being distributed in a circumferential direction of said raceways with their center axes slanting at a predetermined angle to a section including the same axis for said inner and outer rotation bodies, the surface of each intermediate rotation body being in line contact with said inner and outer raceway surfaces; said energizing means energizing either said inner rotation body or said outer rotation body in the axis line direction to narrow the gap of said raceways; said inner rotation body and said outer rotation body respectively having annular members at far ends of the bodies, which face each other in said axis line, to bring the movement of said intermediate rotation bodies in said axis line direction to a stop; and a retainer for retaining said intermediate rotation bodies so that they cannot contact one another, said retainer extending axially beyond end faces of said intermediate rotation bodies, said annular members being positioned so that they can contact the end faces of said intermediate rotation bodies.
