Claims

[Scope of utility model registration request]

a fan drive shaft that is rotatably driven by an engine; a rotating disk that is integrally attached to the fan drive shaft, has an uneven portion on its outer edge, and has a first oil hole formed inside the uneven portion; A fan is attached to the outer periphery and is rotatably attached to the fan drive shaft in a state covering the rotating disk, and an uneven surface adjacent to the uneven portion of the rotating disk is formed on one of the opposing inner wall surfaces. and an inner wall surface that is attached to the inner periphery of the fan main body in a state opposite to the one inner wall surface of the fan main body with the rotating disk sandwiched therebetween, and that is connected to the other inner wall surface of the fan main body. a partition plate that forms an oil chamber therebetween; and a second partition plate that is bored at the outer edge of the partition plate and that guides oil passing between the uneven portion and the uneven surface by centrifugal force to the oil chamber.
an oil hole, and a third oil hole that is bored in the partition plate opposite to the first oil hole and that sends the oil in the oil chamber between the uneven portion and the uneven surface through the first oil hole. a spiral bimetal having one end attached to the other inner wall surface of the fan body and concentric with the fan drive shaft; a valve plate that is swingably attached to the partition plate and has a fan-shaped opening/closing part formed at the tip thereof so as to be in sliding contact with the partition plate and to open and close the third oil hole as the spiral bimetal changes due to temperature changes; A fan clutch.
