Abstract

 手持ち式のグラインダにおいて、粉塵飛散防止のため砥石の側方を覆う砥石カバーを位置調整する場合に、従来特別の規制がなされていなかったため、スピンドル軸回りに回転し過ぎて粉塵飛散防止機能が損なわれてしまう場合があった。本発明では、砥石カバーを位置調整する場合に回転し過ぎを防止して、その粉塵飛散防止機能が確実に発揮されるようにする。  砥石カバー(20)にストッパ突起部(27)を設け、ギヤハウジング(8)側にストッパ当接部(8e)を設けて、砥石カバー(20)を砥石回転方向に約60度回転させた位置でストッパ突起(27)をストッパ当接部(8e)に当接させてその位置調整範囲を規制する構成とする。
