PURPOSE:To adapt a vibration control device to of several kinds of constantly oscillating subjects to be damped by providing weights while arranging a sidewardly extending spring member on a connection member of the damping subject, and providing an elastic arm extending parallelly to the spring member on the connection member for installing a friction controlling member. CONSTITUTION:A connection member 1 is installed on the outside of a pipe P, while a bar spring 8 is pierced through a block 2 extendingly toward both sides in a perpendicular direction to an axis of the pipe P, on both sides of which spring 8 weights 9 are displaceably provided. An elastic arm 10 is extended parallelly to the bar spring 8 upside the block 2, while on both ends thereof rings 11 are installed with a specified functional resistance adjustably in the friction by means of fastening fittings 14. The resonance is avoided applying the principle of a non-attenuation constant oscillation frequency type dynamic damper, so that it is adapted to several kinds of constantly oscillating subjects to be damped. |
