Zusammenfassung:To provide a nozzle for an oral cavity washing device and an oral cavity washing device that allow a nozzle housing having a complicated flow passage shape to be manufactured more easily.SOLUTION: A nozzle 4 for an oral cavity washing device includes a nozzle housing 40 formed with a flow passage P1 having an inflow port P1a and a discharge port P1b. The nozzle housing 40 includes a first molding member 5 formed with a first concave part 512 constituting part of the flow passage P1, and a second molding member 6 formed with a second concave part 612 constituting part of the flow passage P1, which is joined to the first molding member 5. A connection surface 81 of the first molding member 5 and the second molding member 6 extends along a flow passage axis C1 of the flow passage P1.SELECTED DRAWING: Figure 17 【課題】複雑な流路形状を有するノズルハウジングをより容易に製造することが可能な口腔洗浄装置用ノズルおよび口腔洗浄装置を得る。【解決手段】口腔洗浄装置用ノズル4は、流入口P1aと吐出口P1bとを有する流路P1が形成されたノズルハウジング40を備えている。このノズルハウジング40は、流路P1の一部を構成する第1凹部512が形成された第1成形部材5と、流路P1の一部を構成する第2凹部612が形成され、第1成形部材5に接合される第2成形部材6と、を備えている。そして、第1成形部材5と第2成形部材6との接合面81が流路P1の流路軸C1に沿って延在している。【選択図】図17
