<P>PROBLEM TO BE SOLVED: To provide a torque transmission mechanism that can surely transmit torque between a driving shaft and a rotor, and can prevent the passing of fluid between the driving shaft and the rotor. <P>SOLUTION: This torque transmission mechanism includes the cross-sectional circular driving shaft 15, and the rotor 26 having a cross-sectional circular shaft hole 35 in which the driving shaft 15 is pressed, is formed with a press-in fastening part for mutually fastening the rotor 26 and the driving shaft 15 by press-in of the driving shaft 15 to the shaft hole 35, and transmits the torque between the driving shaft 15 and the rotor 26 via the press-in fastening part. The driving shaft 15 has a press-in shaft part corresponding to the press-in fastening part, and the press-in shaft part has a non-cylindrical part 38 for forming a part of an outer peripheral surface on a non-circumferential surface and a cylindrical part 39 having an outer peripheral surface being a circumferential surface. <P>COPYRIGHT: (C)2013,JPO&INPIT |
