PURPOSE:To reduce the quantity of parts and save the labor in assembling by installing an annular stopper so as to be integral and separable onto the outer periphery of a plug and fixing a stopper onto a cylinder in the state where the plug and the stopper are separated. CONSTITUTION:A plug 21 for opening/closing-operating a valve 7 is installed in a cylinder 1. A stopper 24 for suppressing the slip-off of the plug 21 from the inside of the cylinder 1 is installed. After the plug 21 is fitted into the cylinder 1, the stopper 24 is fixed onto the cylinder 1 in the state where the plug 21 and the stopper 24 are separated. Therefore, the quantity of parts can be reduced, and the labor in assembling can be reduced, and the production cost can be reduced drastically. |
