<P>PROBLEM TO BE SOLVED: To provide a torque transmission mechanism capable of transmitting torque between a rotating shaft and a rotor in a wide temperature region even when the rotor is formed of a material having a lower thermal expansion coefficient than that of the rotating shaft. <P>SOLUTION: The torque transmission mechanism is provided for transmitting torque between the rotating shaft 11 and the rotor 12. It includes the rotating shaft 11, and the rotor 12 to be rotated together with the rotating shaft 11. Herein, a fastener 25 is provided which is pressed and fastened into the rotating shaft 11. The rotor 12 is connected to the fastener 25 via a connection member 20. The connection member 20 restricts the rotation of the rotor 12 relative to the fastener 25. The fastener 25 is formed of a material having a lower thermal expansion coefficient than that for the rotor 12. <P>COPYRIGHT: (C)2010,JPO&INPIT |
