Summary:To provide an impact tool that can autonomously control a rotational speed of an output shaft in accordance with a work state.SOLUTION: An impact tool 1 includes a motor 3, an impact mechanism, an output shaft, a control unit 7 and a thrust force detector 9B. The thrust force detector 9B detects thrust force added to an output shaft. The thrust force is a force in a direction along a thrust direction of the output shaft. The control unit 7 executes limiting processing when a thrust force condition relating to the thrust force detected by the thrust force detector 9B is satisfied. The limiting processing includes at least one of suppressing a rotational speed of the output shaft and stopping rotation of the output shaft.SELECTED DRAWING: Figure 1 【課題】作業状況に応じて自律的に出力軸の回転速度を制御可能なインパクト工具を提供する。【解決手段】インパクト工具１は、モータ３と、インパクト機構と、出力軸と、制御部７と、スラスト力検出部９Ｂと、を備える。スラスト力検出部９Ｂは、出力軸に加えられるスラスト力を検出する。スラスト力は、出力軸のスラスト方向に沿った方向の力である。制御部７は、スラスト力検出部９Ｂで検出されたスラスト力に関するスラスト力条件が満たされると、制限処理を実行する。制限処理は、出力軸の回転速度を抑制することと、出力軸の回転を停止させることと、の少なくとも一方を含む。【選択図】図１
