PROBLEM TO BE SOLVED: To provide a rotary cam pressure regulating device, in which, in a case where a pair of face cams are twisted depending on increase in load torque, rotary cams rotatably supported by one face cam are rotated so that rollers are rolled with an extremely stable where the rollers disposed in V-groove faces keep line contact with respect to V-groove faces of rotary cams and V-groove faces of the other face cam. SOLUTION: A friction gearing type transmission device is a pressing force generating device for applying a pressing force to contact faces of rolling bodies depending on load torque acting at least one of an input shaft and an output shaft, by a pair of face cams which are disposed at positions facing each other and in which rolling elements are disposed. One face cam rotatably supports a plurality of rotary cams around an axial center of a face cam body. The rotary cam has a V-groove in which rollers as rolling elements are brought into contact along an axial direction. COPYRIGHT: (C)2005,JPO&NCIPI
