<p>A rotor structure of a permanent magnet type rotary machine wherein a permanent magnet (3) formed cylindrically is fixed to the circumferential section of a rotary shaft (2) so as to transmit a torque acting on the permanent magnet (3) to the rotary shaft (2). The rotor structure is provided with two side plates(4) and a holding ring (5). The side plates (4) formed annularly have the rotary shaft (2) fitted into shaft holes (4a) in an integrally movable manner, are arranged respectively opposite both end faces of the permanent magnet (3), and have U grooves (4c) formed coaxially with the shaft holes, in end faces (4b) opposite the permanent magnet (3). The holding ring (5) formed cylindrically covers the circumferential surfaces of the permanent magnet (3) and the side plates (4), thereby fastening the permanent magnet (3) and the side plates (4) in an integrally movable manner.</p> |
