Claims

[Scope of utility model registration request]

The outer periphery of the end face of a motor case die-cast with cast metal or molded with synthetic resin is connected to the inner diameter end face of a hollow cylindrical venturi case with an inner diameter of a circular cross section through a plurality of support legs. A rotor core is fixedly supported and has an outer circumferential surface facing the inner circumferential surface of the stator core fixed to the inner circumferential portion of the motor case with a small gap therebetween, and a plurality of fan blades are implanted on the outer circumferential surface. A rotor is constituted by a rotating hub and an integral rotor conductor, and the rotor is rotatably supported by the inner diameter of a cylindrical sleeve for bearing holding that is fixedly supported in a cantilevered manner at the center of the end face of the motor case. In an axially thin fan motor that is supported by a shaft, the end of the cylindrical sleeve for holding the bearing is configured to protrude outward from the end surface of the motor case that fixedly supports the cylindrical sleeve in a cantilevered manner. A fan motor characterized by:
