Abstract

PURPOSE: To prevent reversion, by contacting a follow-up magnet and a magnetic substance by suction between the follow-up magnet and the magnetic substance when opening magnetic connection by mounting the magnetic substance to the follow-up magnet side, in a device that transmits rotation by magnetic connection.
CONSTITUTION: A follow-up magnet 4 is downward pulled by mutual suction force between a drive magnet 2 and the follow-up magnet 4 and turns under a condition that an encoder 22 is mounted to a city water meter. When parting the encoder 22 from the city water meter, mutual suction action between the magnets is released, and the follow-up magnet 4 is upward pulled by suction force between the magnetism of another one surface of the follow-up magnet 4 and a magnetic substance 6 and contacts with a lower projected portion 5A of a bearing portion 5. Reversion can be prevented by making contact force at that time larger than the reaction of a spring 14 for instantaneous feed.
