Zusammenfassung:	PURPOSE: To obtain a small-sized fan having high blowing efficiency by integrally forming a bearing support member supported by a flange for supporting an electric motor and an impeller, the flange, a housing, and arms for connecting the flange and the housing, of a synthetic resin. CONSTITUTION: In this fan, a bearing support member (i.e., a bearing tube) 99 for receiving a ball bearing 12 is integrally injection-molded with a flange 4. The bearing support member 99 is coupled with a brushless DC electric motor 5 operated by one or two pulses to continuously operate with high precision and high temperature resistance. A housing 2, the flange 4, arms 3 and the bearing support member 99 constitutes a single synthetic resin part. The bearing support member 99 is provided with shoulder-like additional components 99A, 99B, 99C formed by the other injection molding for the purpose of supporting bearing elements and a stator. A cylindrical passage of an airflow 13 is formed between blades 7 and an inside wall of the housing 2.
