PROBLEM TO BE SOLVED: To prevent water leakage when trying to remove a filter during washing, by preventing the filter from coming off from a filter case easily.SOLUTION: A washing machine includes: a first projection 31 and a second projection 32 provided being deviated in an axial direction at opposing positions on an inner wall of a cylindrical part 26 of a filter case 25; a first groove 33 with which the first projection slides and a second groove 34 with which the second projection slides which are provided on an outer periphery of a cap 22; a first notch 35 provided at the first groove 33 and the second groove 34 for the first projection 31 to pass through; and a second notch 36 provided only at the second groove 34 on the side opposing to the first notch 35 for the second projection 32 to pass through. The first projection 31 is provided on a further front side than the second projection 32 in the axial direction and configured so as to be short in the rotation direction. A length in the rotation direction of the first notch 35 is configured to be shorter than a length in the rotation direction of the second projection 32; thus, a filter does not come off just by one twist operation. |
