Abstract

衝撃式作業工具において、打撃動作後のビットの跳ね返りによる衝撃力の低減に資する技術を提供する。工具本体（１０３）と、長軸方向に直線運動する打撃子（１４３）と、打撃子（１４３）の直線動作を工具ビット（１１９）に伝達する中間子（１４５）と、工具ビット（１１９）がハンマ作業をする際に、反力伝達位置において、工具ビット（１１９）に当接した状態に置かれ、工具ビット（１１９）からの反力が伝達される衝撃吸収用のウェイトと、伝達された反力によって反力伝達位置から打撃子（１４３）側へと移動するウェイトに押されて弾性変形し、これによって当該ウェイトに伝達された反力を吸収する弾性要素（１６５）と、を有し、ウェイトは、中間子（１４５）によって構成されている。
