置。 A first rotating shaft, a cylindrical permanent magnet fixed to the first rotating shaft, and a portion of the first rotating shaft or one end surface of the cylindrical permanent magnet abuts through a washer. a second rotating shaft, and a cylindrical hissing plate fixed to the second rotating shaft and facing the circumferential surface of the cylindrical permanent magnet, wherein a part of the second rotating shaft is When in contact with the first rotating shaft or one end surface of the cylindrical permanent magnet via a washer, one end of the cylindrical hissing plate is lower than one end of the cylindrical permanent magnet. The contact state is maintained by the protruding portion being magnetically attracted to the cylindrical permanent magnet, and the friction torque due to the contact and the hysteresis between the cylindrical permanent magnet and the cylindrical hysteresis are maintained. A rotation transmission device characterized in that rotation is transmitted between the first rotation shaft and the second rotation shaft by hysteresis torque between the plates.
