When the number of penetrating magnetic fluxes between the rotary shafts 1 and 4 increases and the rotary shaft 1 is rotating, eddy currents are generated and electric braking force is generated. This braking force increases as the distance between the disk 2 and the magnet 3.4, which is proportional to the amount of operation of the operating lever 9, becomes smaller, and by adjusting the amount of operation of the operating lever 9, the braking force can be finely adjusted. It becomes possible. Furthermore, the heat generated by the eddy current generated in the disk 2 can be dissipated by rotating the disk 2.
