Zusammenfassung:	A fan (60) including a hub part (61), a blade part (62) and a vibration-absorbing boss (10), all constituent elements of which are injection molded, thereby reducing production costs. The fan (60) has a minimized contact area between the vibration-absorbing boss (10) and the hub part (61) to prevent the vibration-absorbing boss (10) from being deformed by high-temperature heat during insert injection molding of the hub part (61) and the blade part (62) while assuring sufficient strength of the hub part (61).
