ABSTRACT:
An input-side rotary member 20, including an input gear 7, and an output-side rotary member 19, including a torque cam 1 fixedly mounted on an output shaft 12, are provided on the same axis of rotation. The input-side rotary member 20 is provided with an input cage 3 having a plurality of radially extending pockets 30 and balls 9 movably accommodated within the respective pockets 30. The torque cam 1 is provided with a generally annular cam groove 31 in which the balls 9 move rollingly, which groove 31 is of a shape having a distance from the axis of rotation that varies continuously. A presser member 2 is provided with a pressing face 2a by which the balls 9 are urged by a spring element 4. In this way, the input rotation of, for example, an engine can be reduced and then transmitted to a driven device such as an engine auxiliary equipment 102 with respect to the boundary set by a preset torque value.
