<P>PROBLEM TO BE SOLVED: To provide an electric pump capable of reducing vibration and noise caused by the displacement of a rotary shaft of a rotor. <P>SOLUTION: The rotor 31 provided with rotational force by a magnetic flux generated by a stator 30, an impeller 20 fixed to one end (a positive directional end of an x axis) of the rotor 31 in a rotational axis and facing an inlet opening IN in the rotational axis direction, a housing HSG rotatably housing the rotor 31 and the impeller 20, a sliding bearing (the first bearing 8) fixed to the rotor 31 and slidably arranged to the member (a supporting shaft 65, a moving regulating member 50) of the housing HSG side, and an inclining part (a taper 80 or a taper 52) inclining in the rotary axis direction to one of the sliding bearing 8 and the member 50 of the housing side are arranged in the electric pump, and the other of the sliding bearing 8 and the member of the housing side HSG are arranged so as to be able to abut on the inclining part when the rotor 31 moves to the inlet opening IN in the rotational axis direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
