<P>PROBLEM TO BE SOLVED: To provide a filter device capable of filtrating pertinently a liquid flowing through a pipe only by inserting it into the pipe serving as a flow channel of the liquid, and capable of securing a filtration area effective for the filtration as wide as possible. <P>SOLUTION: This filter device is constituted to close a cylindrical one-end part 1 of a main part B constituting the filter device. At least a flange part 4 is provided between the cylindrical both end parts 1, 2 of the body B, to contact with an inner face of the pipe P by elastic deformation and to partition a space inside the pipe P in a liquid-tight state. The first liquid passage part 6 covered with a filter medium 7 is provided in a cylindrical side part 3 between the cylindrical one-end part 1 and the flange part 4, and the second liquid passage part 8 is provided on the other cylindrical end part 2 side of the filter device more than the flange part 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
