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. The reaction causes a radial displacement of a bearing-fitting portion provided with inner and outer bearingsin double layer arrangement, wherein the radial displacement is larger than that of a bearing-fitting portion provided with a bearingin single arrangement, so as to cause unbalanced contact between rollers. In order to prevent this, support stiffness of bearing supportagainst the inter-friction-roller radial pressing reaction is set higher than that of bearing support
