Abstract

To provide a uniaxial eccentric screw pump capable of reducing a manufacturing cost.SOLUTION: A uniaxial eccentric screw pump 1 comprises a stator 60 having a female screw-shaped through hole, and a rotor 80 arranged in the through hole and having a male screw part having a male screw shape and a shaft part connected to the male screw part. The male screw part and the shaft part are integrally formed using resin so that an axial core of the male screw part is parallel to an axial core of the shaft part and an axial core of the male screw part is eccentric to the axial core of the shaft part.SELECTED DRAWING: Figure 3
