Abstract:
 A negative-pressure pump (10) has: an electrically insulating housing (20) that is cylindrical in shape and closed at one axial end by a lid (34); an electroconductive rotating shaft (40) that is disposed inside the housing (20), mechanically and electrically connected to a grounded power source, rotated by the transmission of power from the power source, and positioned so that the rotational center is eccentric from the center of the housing (20), the rotating shaft (40) rotating due to power transmitted from the power source; and an electroconductive vane (50) that is disposed inside the housing (20), supported on the rotating shaft (40) so as to be able to reciprocate in a direction orthogonal to the rotating shaft (40), and electrically connected to the power source via the rotating shaft (40), the electroconductive vane (50) rotating integrally with the rotating shaft (40), having ends (50B) that slide over the inner wall surface (inner peripheral surface (22A)) of the housing, and dividing the interior of the housing (20) into a plurality of spaces to create negative pressure.
