ABSTRACT:
A fan assembly including a hub portion from which blades and a stem are extended respectively radially outwardly and radially inwardly, the hub portion, the blades and the stem being formed of molded plastics and made integral with each other. The stem is connected to an output shaft of fluid coupling by means of bolts each of which passes through a bushing. The bushing having knurling portion at outer surface thereof is inserted in the hole of the stem and the periphery of the hole is melted by heating upon insertion of the bushing therein so as to ensure the connection of the fan assembly to the output member. In case that a spacer is interposed between the stem and a flange of the bush, the spacer is fixedly connected to the bushing.
