Definitions

  • the present invention relates to a ceiling fan suspended from a ceiling.
  • a conventional ceiling fan includes a connecting fitting fixed to a ceiling, and a ceiling fan main body suspended from the connecting fitting via a suspension device.
  • a ceiling fan main body When such a ceiling fan is operated in a state in which it is suspended from a ceiling, a ceiling fan main body may occasionally swing. That is to say, in a conventional ceiling fan, a shaft protruding from the upper part of the ceiling fan main body is movably anchored to the connecting fitting fixed to a ceiling.
  • a shaft protruding from the upper part of the ceiling fan main body is movably anchored to the connecting fitting fixed to a ceiling.
  • not-specified swing components in all directions are generated due to vane weight and unbalanced pitch in a ceiling fan, circulation air generated during operation of a ceiling fan main body, outside wind, and the like, causing a ceiling fan main body to swing non-constantly.
