PROBLEM TO BE SOLVED: To elongate the service life of a rotor itself by slowing the progress of sliding damages on the surface of the rotor due to an abutting member. SOLUTION: This rotor device comprises at least two rotors 1, 3 to be rotated while pressing one against the other and the abutting members 7b, 9b arranged abutting on the surfaces of the rotors, respectively. The abutting members are so arranged as to be dislocated from each other by their widths or greater in the axial direction of the rotors. COPYRIGHT: (C)2005,JPO&NCIPI
