<P>PROBLEM TO BE SOLVED: To provide a vibration control device capable of reducing a dynamic spring constant in such a high frequency region that resonance of a vibration control base body itself becomes dominant. <P>SOLUTION: The vibration control device 10 includes: a cylindrical first fixture 12; a second fixture 14 arranged on the upper side of shaft core part; and the vibration control base body 16 made of rubber-like elastic material interposed between both fixtures, wherein the vibration control base body is formed on a tapered wall part 30 of which the diameter becomes smaller from the first fixture 12 toward the second fixture 14. In the vibration control device 10, by changing the thickness in the circumferential direction C, a thick part 48 having thickness T1 and a thin part 50 having thickness T2 are disposed on the tapered wall part 30 (T1>T2), and the inclination angle θ1 of the thick part 48 is set to be smaller than the inclination angle θ2 of the thin thickness 50. <P>COPYRIGHT: (C)2012,JPO&INPIT |
