PROBLEM TO BE SOLVED: To protect a satellite from longitudinal vibration produced during launch of a rocket, and prevent a clearance loss between the satellite and a fairing from increasing during flight. SOLUTION: The satellite coupling is provided with a lower side ring 11 fixed to a rocket motor 3 in a faring 2 of a rocket 1, and an upper side ring 12 separably connected to a satellite 4. An extension coil spring 13 for giving tensile force to both the rings 11, 12 an air spring 14 which gives a larger pressing force than the tensile force of the extension coil spring 13 to both the springs 11, 12 during launch and the pressing force of which becomes smaller than the tensile force of the extension coil spring 13 after launch, and a fixing mechanism 20 for rigidifying both the rings 11, 12 which are brought close together at the stage only the tensile force is given to both the rings 11, 12, are provided between both the rings 11, 12. In this case, spring constants of both the springs 13, 14 during launch are respectively set so that the natural frequency of a spring system comprising both the springs 13, 14 is smaller than that of longitudinal vibration produced during launch of the rocket.
