Further, the claws F1 and F2 are driven so as to be separated from the coil spring 5, and are returned to the initial position. Then, the grip of the shock absorber 2 by the clamp device C is released. Thus, the shock absorber (not shown) in which the coil spring 5 is properly mounted between the upper seat 3 and the lower seat 4 is taken out.
