VIBRATION ISOLATION DEVICE

摘要

A vibration isolation device (5) comprises an elastic body (3), in which elastic material layers and rigid material layers are alternately laminated on one antoher, and a columnar-shaped lead (4) arranged in a hollow portion (12) defined by an inner peripheral surface (9) of the elastic body (3). A ratio Vp/Ve of a volume Vp of the columnar-shaped lead (4) to a volume Ve of the hollow portion (12), with the columnar-shaped lead (4) not inserted and a load exerted on the elastic body (3), ranges from 1.02 to 1.12.
