摘要：【課題】起動用のスイッチレバーのロックオン機構を備えたディスクグラインダにおいて、従来、ロックオン状態で使用中に誤って電源コードが引き抜かれた場合には、その後の電源復帰時に電動工具が不用意に起動しないように電動モータの動作制御がなされていた。このため、モータ制御用のコントローラが大型化し、その結果コスト高を招く問題があった。本発明は、コントローラの大型化、コスト高を招くことなく電源遮断時にロックオン状態がキャンセルされるようにする。【解決手段】電源遮断時に電磁アクチュエータ30の作動ピン30aを突き出させて、支持台座部3aの前端部からロック部20aを外して起動スイッチ20のロックオン状態を解除する。電磁アクチュエータ30によりロックオン状態を機械的に解除する構成であるので従来のように電動モータのコントローラの大型化、コスト高を招くことがない。【選択図】図2
