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。本発明の衝撃式作業工具（１０１）は、工具本体（１０３）と、打撃動作を行うハンマ作動部材（１１９，１４５）と、ハンマ作動部材がハンマ作業をする際に、反力伝達位置において、ハンマ作動部材（１１９，１４５）からの反力が伝達されるウェイト（１６３）と、伝達された反力によって後方へと移動するウェイト（１６３）に押されて弾性変形し、これによって反力を吸収する弾性要素（１６５）とを有する。そしてウェイト（１６３）と弾性要素（１６５）が工具本体（１０３）の長軸上における同位置において並列状に配置されている。
