Abstract

PURPOSE:To contrive the improvement of durability preventing the leakage of fluid by providing a rotor part mounted into a housing and rotated by a magnetic field of a stator part to propel the fluid. CONSTITUTION:A fan 1 and a rotor 3b of a motor 3 are integrally arranged forming a rotary part, and a mechanism, rotatably supporting this rotary part through a ball bearing mounted to an outer edge part of the fan to be stored in a housing, eliminates a rotary shaft. The rotary part, excepting the rotor 3b, is constituted of non-magnetic material with the housing 1a, and inducing the rotor 3b in the housing 1a by a magnetic field generated by a stator 3a in the outside, fluid is propelled and circulated by rotating the rotary part. Thus, the rotary part is provided independently in the fluid, eliminating the necessity for providing a shaft, so that durability is improved while eliminating the leakage of the fluid.
