In a piston pump, in which the drive shaft is supported by a fixed member so as to be immovable in the axial direction but rotatable around the axis, the drive shaft is supported on both sides across the movement range of the piston. A piston pump characterized by: (2) The piston pump according to claim 1, wherein an output shaft of a motor capable of forward and reverse rotation is connected to one end of the drive shaft via a coupling. (3) The piston pump according to claim 2, further comprising detection means for detecting that the piston is at each outermost position of the movement range and rotating the motor in reverse.
