<p>PURPOSE:To sharply reduce the transmission of vibration by floatingly supporting a weight, laterally crossingly faced to a fluid chamber, and making the kinetic magnification in a high-frequency vibration area nearly zero. CONSTITUTION:A base member 2 and a mounting member 3, which is connected to a vibrating source, are linked by means of a thick-walled, umbrella-shaped elastic member 4, forming a fluid chamber 11 inside them. A weight 7 having an inverse truncated cone part 71 is fitted to the mounting member 3 through an elastic member 8. This weight 7 has a larger effective area than that of the elastic member 4. And, when the mounting member 3 is moved downward, the weight 7 acts so as to draw up a fluid, causing fluid pressure in the fluid chamber 11 to be low, to generate force to draw the elastic member 4 toward the fluid chamber 11 side. Also, due to the downward displacement of the mounting member 3, a downward force toward the base member 2 is generated. Since each of these forces mutually offsets against the other, the kinetic magnification in a high-frequency vibration area becomes nearly zero.</p> |
