Claims

[Scope of utility model registration request]

A rotating body that rotates integrally with the propeller shaft is fixed to the outer periphery of the propeller shaft, a fixed shaft is disposed coaxially with the propeller shaft, and a rotating sliding body is arranged on the outer periphery of the fixed shaft to face the rotating body. loosely inserted, one end of the flap opening/closing rope is wound around the outer periphery of the rotating sliding body, and a magnet body that magnetically connects the rotating body and the rotating sliding body is attached to either of the rotating body and the rotating sliding body. Providing means for separating the rotating sliding body from the rotating body against the magnetic force of the magnet body by the thermal deformation force of a shape memory alloy spring that is heated as the propeller shaft rotates and slides; Furthermore, the ventilation fan is characterized in that the rotary sliding body is provided with a clutch for stopping rotation of the rotating sliding body.
