Claims

[Scope of utility model registration request]

A cap, which has an insertion hole in the center of the bottom wall with a smaller diameter than the inner diameter of the opening, is fixed to the opening of the bottomed hollow outer cylinder. An elastic hollow ring body is installed in the cap from the lower part of the peripheral wall to the peripheral edge of the insertion hole on the inner surface of the bottom wall of the cap, and between the deep bottom of the inner cavity and the end face of the elastic hollow ring body on the back wall side. A hollow inner cylindrical body with a bottom is slidably fitted in the axial direction, the open end face of the inner cylindrical body is brought into close contact with the end face on the deep side of the elastic hollow ring body, and the bottom wall of the outer cylindrical body A tightening bolt is screwed into the center so that it can move forward and backward from the outside, and the tip of the bolt is brought into contact with the outer surface of the bottom wall of the inner cylindrical body, and is also airtightly fixed to the peripheral wall of the inner cylindrical body. A connecting pipe extending outward in the radial direction is communicated with the inner cavity of the inner cylinder, and the connecting pipe is connected to the outside of the outer cylinder through a long groove formed in the peripheral wall of the outer cylinder. A connector for injecting and discharging fluid that protrudes into.
