Abstract

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