PURPOSE:To improve durability by providing a stopper block between an inner cylinder metal fitting and an outer cylinder metal fitting and preventing excessive deformation between these metal fittings. CONSTITUTION:Two concave portions 16, 16 are formed on a rubber elastic body 14 disposed between an inner cylinder metal fitting 10 and an outer cylinder metal fitting 12 at positions symmetrically with the inner cylinder metal fitting 10 therein, and opened on the outer peripheral face of the rubber elastic body 14 respectively. Stopper blocks 22 made of rubber material are placed on the openings and fixed between the opening of the concave portions 16 and the outer cylinder metal fitting. The stopper blocks play a role of regulating elastic deformation amount of the diameter direction of the rubber elastic body 14 based on the contact with the bottom of the concave portions 16. |
