ことを特徴としたポンプのピストン。In a pump piston, which is provided inside a part of a covered cylindrical cylinder having conduits attached to the upper and lower lid parts, and whose outer peripheral part is in airtight contact with the inner peripheral surface of the cylinder part and slides in the vertical direction, A shape center two member in which upper and lower small disc parts each having a diameter smaller than the diameter of the large disc part by a predetermined dimension are arranged concentrically on the upper and lower surfaces of a large disc part having a predetermined diameter, and a cross section facing upward. A spring is provided to widen the opening of the U-shaped circular synthetic resin molded body, and the inner peripheral surface is in contact with the outer peripheral surface of the upper and lower small circular plates of the center member, respectively. The opening has upper and lower sealing members attached with the opening facing in the opposite direction to the large disk portion, and upper and lower presser thin plates attached to the upper and lower surfaces of the center member to prevent the sealing members from falling off.
