At the same time, a shelf part 8 is formed in the lower part of the lower steeply inclined receiving part 7, and an upper steeply inclined fitting part 9 is formed on the outside of the fitting part 4.
, a gently inclined fitting part 10 and a lower steeply inclined fitting part 11 are continuously formed, and the upper steeply inclined fitting part 9 and the lower steeply inclined fitting part 11 of this fitting part 4 are respectively connected to the lid holder. The first part is fitted into the upper steeply inclined receiving part 5 and the lower steeply inclined receiving part 7 of the part 2, and between the gently inclined fitting part 10 of the fitting part 4 and the gently inclined receiving part 6 of the lid receiving part 2. A second gap 12, which is slightly larger than the first gap 12, is formed between the lower end 4a of the fitting part 4 and the shelf part 8 of the lid receiving part 2.
