That is, in the rotation transmitting member 1, the opposing surfaces 7a, 7a of the circular opposing plate portions 7, 7 become the N pole or the S pole, and a pinning force is generated between the circular opposing plate portions 7, 8, so that the rotation transmitting member The member 1 and the rotation transmitting member 2 are coupled by the pinning force, and are stably magnetically coupled while maintaining a gap. That is, when the radial force is applied to the circular opposing plate 7, the circular opposing plate 7 is turned into the circular opposing plate 8.
Is difficult to move. In addition, even if a force is applied in the axial direction, it is difficult to change the gap between the pair of opposed surfaces 7a and 8a. Therefore, the circular opposing plate portions 7 and 8
Is offset with respect to the rotation axis 9, the rotation of one rotation transmission member 1 is relatively
Can be transmitted in a non-contact state. That is, since a concentrated portion of the magnetic flux distribution discontinuous in the rotation direction is formed at a position offset from the rotation shaft portion, the rotation can be reliably transmitted.

However, a permanent magnet (not shown) is provided on the end surface 4a of the shaft portion 4, and pinning is performed so as to face the permanent magnet. It is also possible to provide a superconductor capable of exhibiting the effect and magnetically levitate the rotation transmitting member 2. Further, in the first embodiment, the rotation transmission mechanism is configured to be able to transmit the rotation intermittently by using a clutch structure using an electromagnet, but instead of providing the superconducting coil 10, a circular opposing plate portion is provided. If the rotation transmission member 1 is constituted by a permanent magnet, the rotation of the rotation transmission member 1 can be transmitted to the rotation transmission member 2 without always contacting the rotation transmission member 1 and the rotation transmission member 2. Further, in the first embodiment, the circular opposing plate portion 7,
7 (8, 8) is a pair, but may be two pairs, four pairs, or six pairs.

軸13に伝達されることとなる。In the case of such a configuration, a concentrated portion of the magnetic flux distribution discontinuous in the rotation direction is formed at a position offset from the rotating shaft 12. Therefore, when the rotation shaft 12 is rotated about the rotation axis 9, a pinning force is generated between the rotation transmission member 1 and the rotation transmission member 2, and the opposing surface 7 a is eccentric with respect to the rotation axis 9. Even without doing so, the rotation of the rotating shaft 12 is relatively transmitted to the rotating shaft 13.
