Claims

[Claims for Utility Model Registration] A ring 1 having an inner cylindrical inner peripheral surface 1a, and this ring 1
The rotating shaft 2 is located at the center of the axis, and the outer circumference is formed into an elliptical shape, divided into a plurality of parts perpendicular to the axis, and further biased by a spring outward in the long axis direction of the ellipse. The forces 1, 3a, 3b that fit onto the rotating shaft 2 and the outer peripheries of the cams 3a, 3b, and the cam 3a. A flexible bearing 7 is rotatably engaged with the outer periphery of the long shaft portion of cam 3b, and a flexible bearing 7 is rotatably engaged with the flexible bearing 7, and the inner periphery of the ring 1 is rotatably fitted on the outer periphery of the long shaft portion of cams 3a and 3b. A flexible friction ring 8 that contacts the surface and has a radius smaller than the radius of the inner peripheral surface 1a of the ring 1, and a flexible friction ring 8 that is located between the rotating shaft 2 and the cams 3a and 3b and rotates them both in the rotational direction. A power transmission device comprising a cam mechanism that engages with the cams and urges the cams 3a and 3b outward in the longitudinal direction with a force proportional to the transmitted torque.
