The insertion cylinder comprises: a main cylindrical part 3A in which a main opening 22 is formed; and a sub-cylindrical part 3B in which a sub-opening 31 having an opening area smaller than that of the main opening is formed. In the main cylindrical part, the main opening is closed, and a main closing member 23, in which at least a portion is surrounded by a weakened part 24, is formed. In the sub-cylindrical part, the sub-opening is closed, and a sub-closing member 32, in which at least a portion is surrounded by a weakened part 33, is formed. In the projection piece body, one end part 41a is connected to the main closing member, and the other part 41b is connected to the hook part. The sub-closing member is connected to the projection piece body. |
