PROBLEM TO BE SOLVED: To provide an uniaxial eccentric screw pump capable of suppressing deterioration of pressure delivery performance caused by liquid leakage from a high-pressure side to a low-pressure side. SOLUTION: The uniaxial eccentric screw pump 1, while a male screw shaped rotor 2 directly connected to a drive shaft 3 is rotating, is used to pressure-deliver fluid from suction side to discharge side by performing an eccentric motion relative to a shaft center of a stator 4, and includes a sealing member 16 disposed to hermetically seal sliding portion end of discharge side for self-lubricating bearings 5, 6, and the stator 4.
