    • PURPOSE: To eliminate clogging and extend life of a filter by changing filter paper construction from the conventional corrugated and folded form to a single filter paper system, and employing a construction that peels off remaining dirts deposited on a filtering paper by the restoring motion of the filter paper generated during operation shutdown. CONSTITUTION: In a filter tank of a dry cleaner, a rinsing solvent filter 11 is mounted on a mounting cylinder in place of a filter unit. More specifically, the filter 11 has a main body 14 disposed that has plates 13 having circumferential brims 13b provided with a mounting guide opening 13a at the center, the plates being fixed on both ends of a cylinder 12 made of metallic plate and arranged with small holes 12a to let solvent flow through. A plurality of coil springs 15 pulled in parallel with the cylinder 12 are disposed between the circumferential brims 13b of the plates 13 that are placed opposedly with each other on the main body 14. Further, filter papers 16 are disposed in the main body 14, whose inner sides are in contact with the spring 15, and whose both ends are fixed tightly on the circumferential brims 13b of the plates 13.
