A uniaxial eccentric screw pump in which a male screw rotor with a circular cross section is inserted into a female screw hole with an oval cross section formed in a stator made of an elastic material such as rubber to rotate the rotor eccentrically, A single-shaft eccentric screw pump characterized in that the drive shaft of the motor for rotationally driving the rotor and the rotor are connected by an Oldham coupling within a pump casing in which a suction port or a discharge port is opened. 2 The outer diameter of the floating cam in the middle of the Oldham joint is set so that the radial displacement of the floating cam falls within the range of the joint bodies on both sides, and a cylindrical flexible tube is inserted between the joint bodies on both sides. 2. The uniaxial eccentric screw pump according to claim 1, wherein the pump is connected by a flexible cover, the cover is filled with lubricating oil, and the floating cam is installed inside the cover.
