Abstract
A toroidal type continuously variable transmission transmits a torque from an input disk to an output disk through a plurality of groups of rollers interposed between the input disk and the output disk. Respective carriages for the rollers are connected to one another by a connecting member. A hydraulic actuator collectively applies forces against torque transmission reactive forces respectively received by the rollers to the rollers through the connecting member and the corresponding carriages.
