<p><P>PROBLEM TO BE SOLVED: To provide a filter device which can be given sufficient cleaning effect in cleaning with running water. <P>SOLUTION: The filter device 16 is equipped with a filter body 21, a primary side holder 22, and a secondary side holder 23. The secondary side holder 23 has a secondary side filter chamber 31, a discharge flow passage 32, a discharge opening 33, and a rib piece 34. The discharge opening 33 causes the secondary side filter chamber 31 to communicate with the discharge flow passage 32 at a position eccentric to a center of the secondary side filter chamber 31. The rib piece 34 is extended toward an outer circumferential part 35 of the secondary side filter chamber 31 from the discharge opening 33 and divides the inside of the secondary side filter chamber 31 into a plurality of flow passages 42. The rib piece 34 sets a flow passage diameter smaller for a flow passage having a longer total length among the plurality of flow passages 42 to increase a flow speed of cleaning liquid, and sets a diameter large for a flow passage having a shorter total length to suppress the flow speed of the cleaning liquid. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
