Claims (6)
- モータと、シリンダと、前記シリンダ外周を覆うシリンダケースと先端工具を保持可能な工具保持部と、前記シリンダ内を往復運動可能なピストンと、該ピストンの往復運動力を空気室を介して受け、前記シリンダ内を往復運動する打撃子と、前記シリンダ外周に設けられた該空気室と連通可能な呼吸穴と、前記モータの回転力を、減速歯車を介して受け、回転力を往復運動力に変換して前記ピストンに伝達する運動変換部材と、前記打撃子に打撃され、その打撃力を先端工具に伝達可能な中間子とを有し、前記シリンダに半径方向に突出する突出部、前記シリンダケースに前記工具保持部側に対面し前記突出部と当接可能な当接面、前記シリンダ外周を軸方向において離れた2箇所で保持し前記シリンダの半径方向の位置決めを行なう保持部を設けた打撃工具であって、
前記シリンダの前記突出部を前記工具保持部側端面に形成すると共に、前記一方の保持部を前記突出部外径とほぼ同寸法の内径を有し、前記シリンダケースの前記工具保持部側端面から前記当接面にかけて延びるガイド面としたことを特徴とする打撃工具。 - 前記ガイド面の軸方向長さを、前記他方の保持部が前記シリンダ外周を保持する軸方向長さよりも大きくしたことを特徴とする請求項1記載の打撃工具。
- 前記シリンダ外周上に付勢手段により前記中間子側に付勢され、移動位置に応じて前記呼吸穴外周を開放、閉塞可能なスライドスリーブと、一端が該スライドスリーブの前記工具保持部側端部と当接可能で、他端が前記中間子の前記打撃子側に対面する対面部分と当接可能な連動部材とを設けると共に、前記突出部を複数設け、前記連動部材は前記突出部間に介在する足部を有することを特徴とする請求項1あるいは請求項2記載の打撃工具。
- 前記突出部は、半径方向に突出したフランジ部に複数箇所穴部を設けることにより形成されていることを特徴とする請求項1〜請求項3のいずれか1項記載の打撃工具。
- 前記連動部材は、複数の前記足部を有する第1のハンマホルダと、前記第1のハンマホルダに外周が保持され、前記中間子の対面部分と当接可能な第2のハンマホルダと、前記第1のハンマホルダと前記第2のハンマホルダとの間に配置される緩衝部材を有することを特徴とする請求項3あるいは請求項4記載の打撃工具。
- 前記第1のハンマホルダは前記緩衝部材を覆う円形部を有することを特徴とする請求項5記載の打撃工具。
