Claims

[Scope of utility model registration request]

A pressure sensor consisting of a variable resistor to which a plate is fixed to the rotating shaft is arranged on the back of the stand, and the wind plate is configured to operate based on the change in resistance of the variable resistor when the plate is displaced by wind pressure. An electric fan equipped with a wind pressure sensor that operates a control circuit and controls the speed of the motor.
