PURPOSE:To make it possible to reduce a fan tip clearance and attempt to enhance starting characteristics by transmitting driving force to a rotor on the side of input through a member that absorbs vibration and transmits the driving force from the side of an engine. CONSTITUTION:Driving force of an engine 51 is transmitted to a crank pulley 48, and thence to an input shaft 45 and a rotor 53 on the side of input through a belt 49, a pulley 50, and an universal joint 47 and the rotor 53 is rotated. Rotation of this rotor 53 is transmitted to a rotor 54 on the side of output through silicon oil inside a labyrinth 55, and further to an output shaft 46 for rotating a fan 52. The silicon oil is supplied to a space between the rotors 53, 54 from an oil inlet 56, and discharged to the outside of the rotor 53 from a minute outlet 57 provided on the outer circumference of the rotor 53 by centrifugal force, and the rotation of the fan 52 is controlled by balancing the supplied and discharged quantities of the silicone oil. |
