Abstract
A vibration-damping apparatus for an electric hammer unit is provided. This vibration-damping apparatus is provided with the socalled transatory unit including elastic bars disposed between elastic damper members connected to a tool body and a handle of the electric hammer unit, respectively, for absorbing relative displacement of the elastic damper members caused by vibrations produced by the tool body during use. The vibration-damping apparatus further includes a stopper member attached to the elastic damper member attached to the handle so as to engage a chamber formed in the elastic damper member attached to the tool body for preventing the handle from being dislodged from the tool body even when the handle is swung laterally by a hammer operator. Additionally, each of the elastic bars includes a large-diameter portion and a small-diameter portion so as to allow the large-diameter portion to be deformed toward the small-diameter portion during the relative displacement of the elastic damper members for increasing the life of the bars.
