PURPOSE:To absorb and reduce minor vibrations, restrict the excessive deformation of a vibration-proof rubber body, and extend its life by forming multiple through spaces in the vibration-proof rubber body, and arranging stopper sections in the through spaces. CONSTITUTION:An inner tube 1 and an outer tube 2 are concentrically provided, and a vibration-proof rubber body 3 is connected between them. Spring force adjusting spaces 3a-3d penetrated in the axial direction are formed in the vibration-proof rubber body 3, and the spring constant in this direction is reduced. Stopper sections 41a-41d of a stopper body 4 are inserted into the through spaces 3a-3d respectively, and the holding plate section 42 of the stopper body 4 is coupled and fixed on the outer periphery at the end section of the inner tube 1. Stopper gaps are formed between the stopper sections 41a-41d and the inner peripheries of the through spaces 3a-3d, minor vibrations are absorbed and reduced by the small spring constant, the excessive deformation of the vibration-proof rubber body 3 due to large vibrations is restricted by the stopper sections 41a-41d, and the durability is maintained. |
