Summary:PROBLEM TO BE SOLVED: To join and separate a space vehicle, and also reduce shocking force in separating. SOLUTION: A valve 10 is opened to insert a piston 7 into a piston cylinder 8, and then the valve 10 is closed. Joining force is generated in the fittedly engaging part, between the piston 7 and the piston cylinder 8 by the pressure valance, between atmospheric pressure in the piston cylinder 8 inside and that in outside, in the ground. A spacecraft 1 and a spacecraft puff 3 are joined, because the piston 7 and the piston cylinder 8 are fixed to the spacecraft 1 and the spacecraft puff 3 respectively. The joining force, between the spacecraft 1 and the spacecraft puff 3, is eliminated to separate them, because in the course of launching a rocket, pressure in an outside environment is gradually reduced to expand air in the piston cylinder 8 inside due to a pressure difference to separate the piston 7 from the piston cylinder 8.
