Abstract
Under control of rotation of a crankshaft, a friction rolleris pressed against a friction rollerin a radial direction, so as to achieve torque transmission between the rollers. An inter-roller radial pressing reaction is canceled as an internal force in bearing supports, with no input to a housing. Each bearing supportis formed with a constricted portion at a center section of the bearing support between bearing-fitting portions at end sections of the bearing support, for lowering support stiffness of the bearing support against the inter-roller radial pressing reaction.
