する渦電流式減速装置。 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 attached to the rotor in the axial direction of the rotating shaft. In a speed reduction device in which the width of the drum body of the rotor is extended toward the release position side, the width of the drum body of the rotor is extended toward the release position side, in a reduction gear device in which the length is freely movable from a brake position where the surface fully faces the rotor with a required gap to a release position where the surface completely separates from the rotor in terms of the magnetic circuit. An eddy current speed reduction device characterized in that a cone-shaped inclined surface having an inclination angle of 10 to 45 degrees with respect to the axial direction of a rotating shaft is opposed to a ferromagnetic casing member through a gap to increase the heat dissipation area of the drum body.
