Abstract
The present application discloses an electric fan apparatus comprising a fan, a wind direction shifting plate disposed in front of said fan and adapted to be rotated by the pressure of a wind generated by said fan, a rotary shaft disposed at the center of said wind direction shifting plate and adapted to be rotated integrally with said wind direction shifting plate, a speed governor mechanism interlocked with said rotary shaft and a housing box for housing said speed governor mechanism. With said wind direction shifting plate rotated, a wind may be provided in a wide range. Provision is made to improve the durability of said speed governor mechanism, which is formed with a gear mechanism and a blade. Said housing box contains a liquid into which at least a portion of said gear mechanism is immersed, so that said wind direction shifting plate is rotated at a substantially constant low speed.
