Abstract: <P>PROBLEM TO BE SOLVED: To provide an ion exchange resin-packed filter constituted so that an ion exchange resin-packed state is maintained when water is made to pass through this filter and the ion exchange resin is effectively prevented from being damaged when the water impregnated in the ion exchange resin is frozen at a sub-zero temperature.  <P>SOLUTION: A movable partition plate 9 constituting a pressing unit 6 is made to press the ion exchange resin 2 to the side of a water-permeable plate 4 disposed on the side of a discharge port 1b of this filter by the pressing force of an elastic body 5 so as to keep the resin 2 in a packed state when water is made to pass through this filter at normal temperature. When water 11 enclosed in a space between another movable partition plate 8 and a fixed partition plate 7 is frozen and swollen to push down the plates 8, 9 and a connection part 7 to the inflow side of this filter against the elastic force of the body 5, a gap is created between them and the adjacent resins 2, and thus the damage to the resin 2 is prevented.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
