PROBLEM TO BE SOLVED: To provide a pulse washer which can be easily operated and has a simple configuration.SOLUTION: The pulse washer is characterized in that when an output adjusting lever is rotated in another direction against an urging force of an elastic member, a locking lever is rotated in the other direction against the urging force of the elastic member by the output adjusting lever, and a locking engaging section is engaged with the output holding engaging section to maintain a state where the output adjusting lever is rotated, resulting in maintaining a predetermined output state and when the locking lever is rotated in the other direction against the urging force of the elastic member when the predetermined output state is maintained, the engagement of the locking engaging section with the output holding engaging section is released, and the output adjusting lever is rotated in a single direction by the urging force of the elastic member and recovers to the original state.COPYRIGHT: (C)2012,JPO&INPIT【課題】 操作が容易で、構成も単純なパルス洗浄器を提供すること。【解決手段】 出力調整レバが弾性部材の付勢力に抗して他方向に回動されると、ロックレバが上記出力調整レバによって弾性部材の付勢力に抗して他方向に回動され、ロック用係合部が上記出力保持用係合部に係合することにより、出力調整レバの回動された状態ひいては所定の出力状態が維持され、所定の出力状態が維持されている場合に、ロックレバを弾性部材の付勢力に抗して他の方向に回動させると、ロック用係合部の出力保持用係合部に対する係合が解除され、出力調整レバが弾性部材の付勢力によって一方向に回動されて、元の状態に復帰することを特徴とするもの。【選択図】図3
