ABSTRACT:
An axial resonance attenuating apparatus is formed by a disk-shaped attaching member, which is attached to a rotation shaft of a rotation drum apparatus or one of mass objects which are fixed to the both ends of the rotation shaft. A ring-shaped weight is disposed outside the attaching member, and a linking member which is formed by a plurality of straight and flexible support rods partially links the weight and the attaching member. The respective members are formed as one unit by an acrylonitrile-butadiene-styrene copolymer (ABS resin).
