A speed control device of a toric type infinitely variable transmission having a housing, an input and an output shaft rotatably and coaxially supported by the housing, an input and an output disc fitted on the input and output shafts, respectively, and engaged with the shafts for rotation therewith, the opposed surfaces of the discs cooperating with each other to form a toroidal cavity, left and right traction rollers disposed in the toroidal cavity symmetrically with respect to the axis of the input and output shafts, trunnion devices rotatably supporting the traction rollers and supported by the housing for rotation about pivot axes perpendicular to the axes of rotation of the traction rollers, and pressing means for urging the input and output discs on the traction rollers into engagement with each other and causing a traction force is characterized by a support device for supporting respectively pivot shaft ends so that the pivot shafts of the left and right trunnion devices are slightly tiltable, and a tilting device for slightly moving the support device to left and right and tilting the trunnion devices by a predetermined amount. The support devices include a support link member for connecting the upper and lower pivot shaft ends of each of the left and right trunnion devices using bearing means. The support link members are supported in the housing for slight leftward and rightward movement.
