PROBLEM TO BE SOLVED: To provide a cleaning device capable of removing a solid content in a liquid which has higher density than that of the liquid of the object to be sucked and having a size which can be an object to be sucked by sucking. SOLUTION: The cleaning device for removing the solid content in the liquid is provided with: a cylinder having a bottom surface at its one end; a piston reciprocating in an axial direction inside of the cylinder; a suction port and a discharging port formed on one end side of the cylinder; a suction pipe and a discharging pipe connected to the suction port and the discharging port, respectively; a suction-side check valve which opens so as to make the liquid flow from the suction pipe into the cylinder when the piston slides from the one end of the cylinder toward the other end; and a discharging-side check valve which opens so as to make the liquid flow from the inside of the cylinder out to the discharging pipe when the piston slides from the other end of the cylinder toward the one end. The suction-side check valve is provided inside of the suction pipe. COPYRIGHT: (C)2005,JPO&NCIPI
