Claims

[Scope of utility model registration request]

It is equipped with a non-magnetic conductor disk and a magnetic circuit that forms a magnetic field across the conductor disk at a position offset from the center of rotation, and is capable of responding to the electromagnetic action of eddy currents generated as the conductor disk rotates. In a rotating magnetic damper that generates damping torque, two approximately ring-shaped magnetic yokes are arranged concentrically with a conductor disk and sandwiched in opposition, and two permanent magnets are connected in series to one of the yokes. A rotating magnetic damper characterized in that a magnetic circuit is configured by providing a magnetic circuit in the rotary magnetic damper.
