PURPOSE:To suppress the resonance of an elastic member itself and reduce the transmission of high-frequency oscillations by forming multiple lugs on the inner wall, facing a fluid-sealed chamber, of an elastic member combining a fitting member and a base member to form the fluid-sealed chamber inside it. CONSTITUTION:A mount proper 1 has a base member 10, a fitting member 20, and an elastic member 30, and a diaphragm 40 is provided on the base member 10. In addition, multiple lamella-like lugs 32 are provided in one body with the inner wall 31 of the elastic member 30 facing a fluid chamber 2. The lugs 32 may be formed radially, intermittently, coaxially with the mount 1, and in multiple steps in the radial direction, or may be formed annularly. Thereby, individual lugs 32 are reacted in response to the resonance of the elastic member 30 and the fluid in the fluid chamber 2 is stirred by individual lugs 32, thus the resonance of the elastic member 30 itself can be suppressed by the fluid resistance of individual lugs 32. |
