PURPOSE:To enable an elastic rubber material to decrease its spring out, by spreading end parts of opposed rigid members to be opened in a direction separating from each other while mounting the elastic rubber material. CONSTITUTION:A vibro-isolating rubber, spreading opposed both end parts of an inner cylinder 1 and an outer cylinder 2 to be opened in a direction separating from each other, mounts an elastic rubber material 3 up to said spread opened parts 4, 4 of the cylinders. If assumed l for length of a straight part in the both cylinders 1, 2 and (x) for length of a tilt part starting to spread and open, a proportion of l:x is set to 6:1-5:1. Accordingly, the vibro-isolating rubber, enlarging a sectional area in the opening part of the elastic rubber material 3 as compared with its intermediate part, decreases a spring out of the elastic rubber material 3 to a small amount when external force is applied acting. |
