Abstract

Provided is a waterproof fluid pump including: a motor that is accommodated in a first case and comprises a stator and a rotor, to thus generate a rotating torque; an impeller that is accommodated in a pump housing that is mounted in the first case and that receives the rotating torque of the motor to thus pump fluid; a support shaft to which the rotor and the impeller are rotatably supported and that is fixed to the first case; a first magnet that is fixed to the rotor and is rotated with the rotor; and a second magnet that is fixed to the impeller and is disposed facing the first magnet and that has opposite polarity to that of the first magnet. Thus, fluid may be fundamentally prevented from being introduced into the inside of the motor.
