摘要：
A light-weighted, inexpensive axial-flow fan apparatus which can prevent axial leakage of a magnetic flux of a brushless motor installed therein. A body member of the apparatus or a motor casing on which the motor is supported is made of a non-magnetic material such as a resin material, and a name plate formed from a magnetic seal is applied to the bottom of the motor casing so as to pass a magnetic flux therethrough.
