PROBLEM TO BE SOLVED: To provide a filter device of light weight and toughness by constituting the filter device out of first and second parts molded from synthetic resin and a filter to be received in the parts, and detachably connecting together them with first and second connecting ribs. SOLUTION: A first part F1 is provided with a cylindrical member 11 on the center, and a flange 12b extending from the vicinity of the end part of the cylindrical member 11 outward in the radial direction. A plurality of longitudinal ribs 50 in the axial direction of the cylindrical member 11 are provided from the outer end in the radial direction of the flange 12b, a plurality of ring- like lateral ribs 51 connecting with the longitudinal ribs 60 are provided, and the end parts of the longitudinal ribs 50 are ended at a first connecting rib 52. A second part F2 is constituted into a cylindrical shape out of a plurality of longitudinal ribs 53 extending from the outer end in the radial direction of a cover 12a in the axial direction of a guide member 40 similar to the first part F1, a plurality of lateral ribs 54, and a second connecting rib 55. When the connecting rib 52 of the first part F1 and the connecting rib 55 of the second part F2 are connected together, a filter 14 is contained in them. |
