CONSTITUTION: A cleaner motor has an electric motor part having a rotating shaft(31) with a male screw part(32) to a side, and an impeller(11). The impeller has a lower plate(12) having a through hole through which the male screw part passes; an upper plate(14) having a suction hole(16) formed in the middle to suck a fluid; and plural vanes(17) arranged spirally to the rotating shaft between the upper plate and the lower plate. The upper plate is arranged to one side of the lower plate in a standoff state. An impeller-fixing member(35) of the cleaner motor includes a nut part(36a) having a female screw part(37) formed to the inside, to be screwed to the male screw part, and a washer part(36b) integrally formed to a side of the nut part, to have face contact with the lower plate.
