ABSTRACT:
A shock-absorbing member is fixed to top brackets at the end of a boom opposite to the top of an impact tool. A stopper member is secured to one of the bottom of the shock-absorbing member and the top of the impact tool and the other of the same is formed with a guide recess in which the stopper member is vertically slidable. When the tip of the chisel of the impact tool is pressed hard against an object to be crushed, no turning force will be applied to vibration-damping support members which support the impact tool, thereby preventing the support members from breaking.
