Claims

[Scope of utility model registration request]

A fan drive shaft rotatably driven by an engine; a fan body rotatably attached to the fan drive shaft and having a drum portion concentric with the fan drive shaft and provided with a fan on the outer periphery; It is attached to the fan drive shaft via a bracket in a state facing the inner circumferential surface of the drum section, and is filled with a fluid whose volume changes depending on temperature changes. a cylinder having a piston that moves toward and away from the cylinder; and a cylinder that is connected to the tip of the piston of this cylinder and comes into contact with the inner circumferential surface of the drum part as the piston expands as the temperature of the fluid rises, and the fan drive shaft connects with the fan drive shaft. A fan clutch comprising a coupling shoe that connects the fan body.
