| 摘要 | A uniaxial eccentric screw pump includes: a stator 32 having a female threaded inner peripheral surface; a rotor 33 configured to be insertable into the stator 32, and formed of a male threaded shaft body; an exterior body 31 configured to be movable between a first position where the exterior body 31 is capable of compressing the stator 32 and a second position where the exterior body 31 at least alleviates a compression state of the stator 32; and guide members 55, 56 configured to restrict a movement of the exterior body 31 in a circumferential direction of the stator while allowing a movement of the exterior body 31 in a radial direction of the stator by guiding an end portion of the exterior body 31. | ||||||
