Abstract

A pump device comprising a pump housing including a fluid chamber for inhaling a fluid flowing through the fluid chamber via an intake port and discharging the fluid to an outside via a discharge port, a motor housing including a stator, a shaft whose one end projects into the pump housing and to which an impeller is assembled and whose the other end is rotatably supported by a first bearing portion within the motor housing, a rotor assembled to the shaft and facing the stator, and a bearing plate disposed between the pump housing and the motor housing and including a second bearing portion rotatably supporting the shaft characterized in that the bearing plate is formed by a first fluid passage for leading the fluid to the bearing plate.
