We form recesses in the PFET region in the substrate adjacent to the PFET second spacers. The mutually opposing end portions of the pair of journal portions are connected together by a reinforcing member and the power roller is interposed between the eccentric portion of the trunnion and the reinforcing member, thereby being able to prevent the deformation of the trunnion due to a load applied thereto from the input and output disks through the power roller.
