PURPOSE:To change the supporting characteristics of a mounting device by a constitution wherein an elastic body having a fluid chamber inside is provided with an outside force applying means changing the form of the elastic body from outside, and thereby the quantity of the change in the form of said elastic body is adjusted to change the internal pressure thereof. CONSTITUTION:A power unit 14 is fixed on the upper surface of a first disc- shaped bracket 12 by a bolt 13, while a second disc-shaped bracket 15 is fixed on the lower surface to a car body 17 by a bolt 16. An elastic body 18 made of rubber is interposed between the above two brackets, and a fluid chamber 23 is firmed inside the elastic body 18, while a band 24 serving as an outside force applying means is wound round the outer periphery of the central part of the elastic body 18. By engaging the fastener 26 of the band 24 selectively with any one of engagement holes 25a, 25b... the central part of the elastic body 18 can be narrowed down arbitrarily. Thereby the internal pressure of the elastic body 18 is changed, and thus the supporting characteristics thereof can be changed. |
