Abstract
Provided is a water pump including a supporting structure for an impeller having a lower manufacturing cost and having reduced noise and vibration characteristics compared to a conventional water pump including a supporting structure for an impeller. The water pump including a supporting structure for an impeller includes: a shaft; an impeller having the shaft inserted into a center of the impeller and rotating together with the shaft to discharge an introduced fluid; a core formed on an outer circumference of the shaft; a magnetic material formed on an outer circumference of the core and forming a magnetic field rotating the shaft connected to the core and the impeller; a pump housing the shaft, impeller and core; and a supporting member installed between an end of the shaft and the pump housing to support the shaft.
