PROBLEM TO BE SOLVED: To provide a lid configured so that leveling work can be smoothly performed, reducing adhesion of powder to a leveling part, and suppressing an increase in manufacturing costs by simplifying a structure.SOLUTION: A lid is provided with a fixed lid part 9 and an opening/closing lid part 11 swingably connected to the fixed lid part 9 via a hinge part 10. A leveling part 12 projecting vertically downward is provided along a boundary between the fixed lid part 9 and the opening/closing lid part 11. A first foldable groove 16 and a second foldable groove 17 extending along both sides of the leveling part 12 are provided at the hinge part 10. When the opening/closing lid part 11 is swung via the hinge part 10, the leveling part 12 extends obliquely over an opening part 3 opened by the opening/closing lid part 11 in association with the bending of the first foldable groove 16 and the second foldable groove 17. |
