PROBLEM TO BE SOLVED: To provide a filter device capable of allowing components which may impair performance if removed from a case, to be easily attached to the case, as well as preventing the components from being removed from the case.SOLUTION: In the filter device, an inner cylinder 20 having a substantially cylindrical shape is inserted into a case 11 to cause a receiving part 11b having a substantially cylindrical shape and formed with a claw 11c to be inserted along the inner cylinder 20 so that the claw 11c is fitted into a hole 26. A filter element 30 is inserted into the case 11 to cause the inner cylinder 20 to be inserted along an inner peripheral surface of a filter-medium 31 while an end member 33 is inserted along a receiving part 12.SELECTED DRAWING: Figure 1 |
