The present invention relates to a vibration-proof apparatus of a handle for a drilling hammer, but combining the first to the third connecting piece in the handle case on the first to third fixing piece formed at the end of the hammer drill body with a bolt, the grill of the hammer drill and in the first connecting piece of the close position, to form a one and hold the groove space small cylindrical spring and a large cylindrical first fixed convenience long hole was embedded a first anti-vibration member which are integrated by inserting a buffer material of a soft rubber between the spring binding while fastening with a bolt, and the second connecting piece is to form a one and hold the groove space combined with bolted to the second fixed convenience long hole was embedded a second anti-vibration member of a hard rubber and a combination of the hammer drill the ball integral with the third engagement piece is in the binding site of the hammer drill of the body and the handle by configuring combine stably the connecting piece to the bolt To a large vibration is absorbed by a first vibration means small vibrations claim to be absorbed by the second anti-vibration means prevent the vibration that occurs during use of the hammer drill which is directly transmitted to the operator and give ease operator fatigue .
