PURPOSE: A fluid pump having a complete waterproof structure is provided to omit a separate waterproof process by completely separating a driving portion with a driven portion.;CONSTITUTION: A fluid pump having a complete waterproof structure comprises a pump upper case(15), a pump lower case(14), an electric motor(20), a driving part(30), a driven portion(40) and an impeller(43). In the pump upper case, an inlet port(15a) in which the fluid is induced is arranged in the one-side end center and a vent(15b) in which the induced fluid is discharged is extendly formed. The pump lower case forms fluid flow passage(P) is formed in the inside along with the pump upper case. The driving part is formed into one body with the rotor of the electric motor. The driven portion is magnetically coupled in the driving gear while being arranged inside the fluid flow passage. The impeller is formed into one body with the driven portion and is rotatably supported in the fluid flow passage which locates in the bent portion between the vent and inlet port.;COPYRIGHT KIPO 2012
