PROBLEM TO BE SOLVED: To prevent the bubbles generated in the washing tank from lifting the refuge filter (filter for dishwasher). SOLUTION: A filter member 371 is formed by partially varying the rate of opening. The rate of opening at the main board part 373 and an inclined part 374 is set at about 50% and that at a fixed part 376 at 0%. Out of an overhang part 375, the rate of opening at the boundary part 378 with the fixed part 376 on the front side and on the rear side is set at about 25% and that at the parts other than the boundary part 378 at about 50%. This can make the parts with the smaller rate of opening heavier, thereby achieving an increase in the weight of the refuse filter as a whole. COPYRIGHT: (C)2005,JPO&NCIPI
