A fan seat (30, 30') includes a basis (31) with a vertical extending tubal
portion (32) having a pair of flanges (33) integrally formed on opposite
ends of an inner circumferential surface thereof, and a bearing set (34,
34') located in the tubal portion and sandwiched between the flanges. The
bearing set includes a tube (36) and a pair of bearings (38) firmly
secured in opposite ends of the tube. A method for producing the fan seat
includes the following steps: providing a mold (50) with a cavity (53),
locating the bearing set in the cavity with a space (60) formed between
the bearing set and the mold corresponding to the tubal portion,
injecting molten material into the space, and cooling the molten material
whereby the molten material congeals into the tubal portion and
integrates with the tube.
