In addition, the base portion 25 of the peripheral wall portion 23 has a constricted shape that protrudes radially inward along the circumferential direction at an intermediate position in the axial direction of the cylindrical body 21, and is standing on the bottom wall portion 22. The shape retention of the cylindrical body 21 can be ensured by increasing the rigidity of the portion 23 (side wall portion 24). Furthermore, since the bottom wall portion 22, the base portion 25 of the peripheral wall portion 23, and the lower portion 26 a of the curved portion 26 are thick portions, the rigidity of the bottom wall portion 22 and the peripheral wall portion 23 can be increased to increase the rigidity of the cylindrical body 21. Shape retention can be secured. Moreover, since the upper side 26b of the bending part 26 is a thin part, the cylindrical body 21 can be reduced in weight. In addition, a plurality of reinforcing ribs R are formed on the inner surface of the cylindrical body 21, and the shape retaining property of the cylindrical body 21 can be ensured by increasing the rigidity of the cylindrical body 21.

It is also possible. For example, the bending portion 26 is configured to have a constricted shape that protrudes inward in the radial direction (front-rear direction) along the circumferential direction (up-down direction) at the central portion in the axial direction of the cylindrical body 21. In the cleaning tool case 20, since the curved portion 26 has the constricted shape, the rigidity of the side wall portion 24 can be increased and the shape retaining property of the cylindrical body 21 can be ensured.
