Claims

[Scope of utility model registration request]

A rotor is fitted to one end of the rotating shaft, and a support ring with a plurality of permanent magnets arranged around it so that the polarities of adjacent magnets are opposite to each other is inserted in the axial direction of the rotating shaft. In a reduction gear device in which the pole faces can move back and forth from a position where they magnetically completely oppose the rotor with a required gap to a position where they completely separate from the rotor, the support ring has a space that allows the support ring to freely move back and forth. The cylindrical part of the rotor is formed by the combination of the cylinder and the inner cylinder, and the cylinder ends of the outer cylinder and the inner cylinder are connected by a number of arms arranged radially and elastically supported by springs at the ends of the inner cylinder. The rotor of an eddy current reduction device.
