PURPOSE:To reduce press-fitting time and to prevent rubber from tearing or becoming rugged at the end by a method wherein when an elastic body such as rubber or the like is forced into a hole by a pusher it is pushed oscillating the arm-tie. CONSTITUTION:When into an gap 3 between an inner ring 2 and a circular outer ring 1 arranged coaxially with the inner ring is inserted under pressure a ringed rubber 4 having a larger thickness and a suitable press fit allowance to the gap 3 for assembling each other, an oscillation generator 10 is connected to the pusher 9 for the rubber 4 and the rubber is pushed by presses 11, 12 oscillating the pusher 9. |
