Subsequently, the actuator 400 is inserted into the fixing unit 300. At this time, the hook 410b having an inclined forward surface is inclined elastically by the incision groove 410a formed at one end of the periphery. As a result, the fixing protrusion 310 may be easily passed through the fixing protrusion 310 formed on the inner circumference of the fixing unit 300 to enter the fixing unit 300. In the inserted actuator 400, the hook 410b having a vertically retracted surface is caught by the fixing protrusion 310 of the fixing unit 300, thereby preventing the detachment.

After inserting the actuator 400, when the pipe 220 is formed with the locking groove 230 is formed in the outer periphery of the end portion, the pipe 220 enters and closes the sealing ring 350, and at this time, the locking groove The locking piece 330a of the stopper 330 is caught and fixed to the connection 230 by a pipe.
