To obtain a washing device excellent in washing effect and texture with a simple configuration.SOLUTION: A washing device S includes: a body H which has a cylindrical internal space E; a nozzle N which has a first seal section G1 which abuts on an inner peripheral wall Hb of the body H and makes a part of the internal space E as a pressurization chamber E1 and a first receiving surface Ne on which pressure of a discharge chamber E2 of fluid R and fluid R of the pressurization chamber E1 acts toward an elongation position Q1 and moves between a storage position Q2 and the elongation position Q1; an energization section B1 which energizes the nozzle N toward the storage position Q2; a plunger P which has a second seal section G2 which abuts on the nozzle N and partitions the discharge chamber E2 and the pressurization chamber E1, a second receiving surface Pb which receives pressure from fluid R of the pressurization chamber E1 and an abutting section which abuts on the nozzle N in the elongation/storage direction and is movable relatively to the nozzle N and the body H; and a position regulation section Hc which determines the position of the plunger P so that the second seal section G2 is opened when the nozzle N is located at the elongation position Q1.SELECTED DRAWING: Figure 3
【課題】構成が簡単で洗浄効果および質感に優れた洗浄装置を得る。【解決手段】筒状の内部空間Eを有する筐体Hと、筐体Hの内周壁Hbに当接して内部空間Eの一部を加圧室E1とする第1シール部G1および流体Rの吐出室E2および加圧室E1の流体Rの圧力が伸長位置Q1に向けて作用する第1受面Neを有し格納位置Q2と伸長位置Q1との間で移動するノズルNと、ノズルNを格納位置Q2に向けて付勢する付勢部B1と、ノズルNに当接して吐出室E2と加圧室E1とを仕切る第2シール部G2および加圧室E1の流体Rから圧力を受ける第2受面Pbおよび伸長・格納方向にノズルNと当接する当接部を有しノズルNおよび筐体Hと相対移動可能なプランジャPと、ノズルNが伸長位置Q1にあるとき第2シール部G2が開放されるようプランジャPの位置を決定する位置規制部Hcと、を備えた洗浄装置S。【選択図】図3
