れたことを特徴とするカツプリングフアン。[Claims for Utility Model Registration] A fan body comprising a substantially cylindrical boss portion and a plurality of wing portions that protrude substantially radially from the outer peripheral surface of the boss portion and are spaced apart in the circumferential direction, and the boss portion and a substantially ring-shaped mounting plate that is fixed to the coupling plate and attached to the operating part of the coupling, and the rotational force of the drive shaft of the coupling is transmitted to the operating part by the viscous resistance of the liquid sealed in the coupling. Preferably, in the coupling fan in which the mounting plate and the fan body rotate, at least one of the mounting plate and the boss portion has a fin extending transversely to the rotation direction on a side opposite to the coupling; The mounting plate and the boss portion have an air passage provided near the fin and penetrating from one surface of the boss portion to a surface of the mounting plate facing the coupling, and rotation of the fin causes air to be drawn from the air passage. A coupling fan characterized in that it is configured to flow toward the coupling side.
