Claims

[Claims for Utility Model Registration] 1. A driving-side magnetic pole having an excitation coil and connected to an input shaft, and a driven body connected to an output shaft arranged on an inwardly facing surface of this magnetic pole with an air gap in between. , a side plate connected to one of the magnetic poles and the other supported on the base of the driven body via a bearing, and magnetic powder stored in a gap formed in the opposing part of the magnetic pole and the driven body. The coupling device is characterized in that the magnetic pole and the input shaft are coupled by keying with the lower end of a magnetic pole support integrally provided on the opposite side of the magnetic pole in the direction of the input shaft. Magnetic coupling device. 2. The magnetic coupling device according to claim 1, wherein the magnetic pole support and the input shaft are coupled by spline fitting instead of key coupling. 3. The magnetic coupling device according to claim 1 or 2, wherein an auxiliary part is added to the magnetic pole to compensate for the flywheel effect caused by the magnetic pole support.
