<P>PROBLEM TO BE SOLVED: To provide a low-cost switch machine capable of efficiently utilizing drive force of a drive source. <P>SOLUTION: The switch machine 1 is provided with: an operating lever 7; the drive source 3, which drives the operating lever 7; a speed reducing mechanism 13 having a plurality of stages of speed-reducing parts, which reduce the drive force of the drive source 3 and transmit the reduced force to the operating lever 7; and a torque transmitting device 15, which is disposed between the plurality of stages of the speed-reducing parts. The torque transmitting device 15 is a non-contact power transmitting mechanism utilizing an eddy current generated by a rotating magnetic field and increases torque to be transmitted as slipping rotation speed is increased. <P>COPYRIGHT: (C)2013,JPO&INPIT |
