Abstract

【課題】　打撃工具において、打撃動作後のビットの跳ね返りによる衝撃力の吸収構造に関し改良された技術を提供する。 【解決手段】　本発明の打撃工具は、工具本体１０３と、ハンマ作動部材１１９，１４５と、打撃子１４３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、ハンマ作動部材からの反力が伝達されるとともに、当該伝達された反力によって反力伝達位置からハンマ作動部材の長軸方向と異なる方向へと移動するウェイト部１６３と、弾性変形可能な弾性要素１６５と、を有する。ウェイト部１６３は、反力が伝達される前の第１の状態と、反力の伝達によってハンマ作動部材の長軸方向と異なる方向へと移動される第２の状態との間で状態が変化する構成とされる。また、弾性要素１６５は、ウェイト部１６３が第１の状態となるように付勢力を作用し、ウェイト部１６３が反力によって第１の状態から第２の状態へと変化する際、ウェイト部１６３に押されて弾性変形することで当該ウェイト部１６３に伝達された反力を吸収する。
