The open end of the inner cover 5 faces the end face of the bottom wall of the bottom shell 1, which is the end face of the open end of the inner cover 5. The end face of the open end of the inner cover 5 is in contact with the bottom wall of the bottom shell 1 to achieve a sealed contact between the inner cover 5 and the bottom wall of the bottom shell 1.

[0047] The outer cover 7 is open at one end close to the bottom wall of the bottom shell 1 and covers the outer part of the inner cover 5. The open end of the outer cover 7 faces the end face of the bottom wall of the bottom shell 1, which is the end face of the open end of the outer cover 7. A first step 6 is arranged on the outer side wall of the inner cover 5. The open end of the outer cover 7 is located on the side of the first step 6 away from the bottom wall of the bottom shell 1. The end face of the open end of the outer cover 7 is in contact with the surface of the first step 6.
