To reduce work manhours, and to simplify installation operation at a construction site, while excellently exhibiting the function of checking the relative separation movement in the flow passage direction of both cylinder parts, by rationally remodeling mainly an engaging member installed in an engaging object part of both cylinder parts.
The engaging object parts 19 and 20 mutually communicating in the cylinder diameter direction in a state of opening on the inner side in the cylinder diameter direction, are formed in a specific part in a fitting connecting part of both cylinder parts 1 and 2 fitted and connected in a state of constituting a flow passage. The engaging member 21 checking the relative movement in the flow passage direction of both cylinder parts is inserted and installed from the inner side in the cylinder diameter direction over both engaging object parts 19 and 20. A slipping-out restraining means E is arranged for applying resistance to the slipping-out movement in the cylinder diameter direction of the engaging member 21 installed in the engaging object parts 19 and 20 of both cylinder parts 1 and 2.
