PURPOSE:To satisfactorily absorb the inertial force by relative speed and the relative position at the time of docking by providing a spring protruding and recessing driving means for protruding and recessing a coil spring provided on the top end part of a probe fitted to a probe insert part. CONSTITUTION:Docking ports 3, 4 are provided in the opposite parts of a space craft and a space station are airtightly closed by hutches 5, 6, and an expansion bonding device A and a holding device B are provided in the center of each hutch 5, 6. The expansion connecting device A is formed of a coil spring 9 freely inserted into a column 7 and a spring protruding and recessing driving means 10. The expansion connecting device A is provided with a probe 19 fitted to the top end part of the coil spring 9, which can be fitted to a funnel probe inserting part 37 in the holding device B. The driving motor of the spring protruding and recessing driving means 10 is operated, and this rotation is transmitted to a drive shaft 11 through a decelerator device 12, whereby the top end of the coil spring 9 can be advanced from the hutch 5 by the action of a spiral channel 11a.
