<p>A variable spring constant type damper filled with viscous fluid (2) which has a damping effect over a wide frequency band from a low frequency band to a high frequency band and which suppresses a resonance magnification at a resonance frequency of a supported body, wherein the wall thickness of a flexible portion (9) made of an elastic body such as rubber connecting a cylindrical portion (8) and a stirring portion (3) is varied, whereby the spring constant is allowed to depend upon the amplitude. <IMAGE></p> |
