ABSTRACT:
A coupling fan includes a fan body, a coupling and a mounting plate. The mounting plate includes a substantially ring-shaped base member and a substantially strip-shaped movable member having spring elasticity. The base member is connected to a boss of the fan body or an operating member of the coupling. The movable member is connected to the base member at its one end, and it is further connected to the boss of the fan body or the operating member of the coupling, to which the base member is not connected, at its another end. With this construction, not only vibrations of the fan body and the coupling are absorbed by the movable member, but also an overall inside diameter of the mounting plate can be made greater. Namely, a coupling having a larger outside diameter can be employed, and accordingly the cooling efficiency of the coupling can be improved. Hence, the coupling fan can be improved in its durability.
