Under control of rotation of a crankshaft 41, a friction roller 32 is pressed against a friction roller 31 in a radial direction, so as to achieve torque transmission between the rollers 31, 32. An inter-roller radial pressing reaction is canceled as an internal force in bearing supports 23, 25, with no input to a housing 11. Each bearing support 23, 25 is 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. |
