PURPOSE:To improve the buckling limit of an elastic member without changing its material by forming annular lugs on at least one of inner and outer walls of the elastic member combining a fitting member and a base member to form a fluid-sealed chamber inside it. CONSTITUTION:A mount proper 1 has a base chamber 10, a fitting member 20, and an elastic member 30 combining them, and a diaphragm 40 is provided on the base member 10. In addition, annular lugs 32 are formed coaxially with the mount 1 and in multiple steps in the radial direction in one body with the inner wall 31 of the elastic member 30 facing a fluid chamber 2. Thereby, the annular lugs 32 suppress the reaction of the mount 1 in the radial direction as the load is increased, thus the buckling limit of the elastic member 30 can be improved. |
