PURPOSE:To double the durability performance of an engine by housing an inner cylinder eccentrically in an outer cylinder so as to form a durable structure by means of a support member interposed between the outer surface of the inner cylinder and the inner surface of the outer cylinder at the position where both cylinders are farthest from each other. CONSTITUTION:An inner cylinder 2 is eccentrically housed in an outer cylinder 1 and a support member is interposed by utilizing the spot where both cylinders are farthest from each other. Accordingly, the stain of rubber on the surface becomes smaller than that on the case of concentric arrangement because of longer support member 3 when the inner cylinder 2 makes vibration in the direction for applying shearing deformation to the support member 3, and the support member 3 can be formed in thick layer even up to the bonded part. Thus, the durability performance can be doubted. |
