Abstract

PURPOSE:To enhance a vibration-damping effect by a method wherein a screw rod provided with stirring vanes is rotatably placed in a main casing containing a pluverulent material, and an intermediate part of the rod is engaged with a threaded hole provided at an end of an auxiliary casing. CONSTITUTION:A main cylinder 1 connected to a structure is partitioned by an intermediate wall 1a, with a casing 1b provided on one side thereof and a sleeve 1c formed on the other side. The pulverulent material 2 is sealed in the casing 1b, whie an auxiliary cylinder 3 connected to an object of vibration damping is inserted in the sleeve 1 in such a manner that the cylinder 3 can be freely moved relative to the sleeve 1c in the axial direction. The screw rod 4 is engaged at its intermediate part with a ball nut 3a provided at the inside end of the cylinder 3, one end of the rod 4 rotatably penetrates through the wall 1a and passes through the interior of the casing 1b of the main cylinder 1 to be supported by the end wall of the main cylinder 1, while the other end of the rod 4 is inserted in the auxiliary cylinder 3. The end part of the screw rod 4 placed in the casing 1b is fitted with the stirring vanes 4a extending radially in four directions.
