Claims

[Claims for Utility Model Registration] (1) A shaft, an inner cylinder disposed on the outside of the shaft and interlocked with the rotational movement of the shaft, and an inner cylinder disposed on the outside of the inner cylinder with its inner surface facing the outer surface of the inner cylinder. It comprises an outer cylinder facing each other, and magnetic particles interposed between the inner cylinder and the outer cylinder, one of the inner cylinder and the outer cylinder is formed of a magnet, and a surface of the inner cylinder and the outer cylinder facing the other is provided with a magnetic particle. A torque limiter characterized in that the other of the inner cylinder and the outer cylinder is made of a ferromagnetic material and is pole magnetized. (2) A shaft, an inner cylinder arranged on the outside of the shaft and interlocked with the rotational movement of the shaft, an outer cylinder arranged on the outside of the inner cylinder with its inner surface facing the outer surface of the inner cylinder, and this inner cylinder. It is characterized by comprising magnetic particles interposed between the cylinder and the outer cylinder, wherein both the inner cylinder and the outer cylinder are formed of magnets, and the mutually opposing surfaces of the inner cylinder and the outer cylinder are multipolar magnetized. torque limiter.
