PROBLEM TO BE SOLVED: To provide a mist generator avoiding a large swirling flow of a liquid of a liquid storage part during rotation of a rotor, and suitably inhibiting variation of the mist generation amount caused by the swirling flow and generation of noise.SOLUTION: A mist generator MG1 protrudes upward from a bottom surface 14a of a liquid storage part 14, and it has a protrusion part 4 for inhibiting a swirling flow, and the whole or one part of the protrusion part 4 is arranged to be immersed in a liquid of a liquid storage part 14 inhibiting the liquid of the liquid storage part 14 from swirling around the axial part 21 during rotation of a rotor 2, and the protrusion part 4 has a standing surface 40 standing upward from the bottom surface 14a of the liquid storage part 14 at a position near the outer peripheral surface 21a of the axial part 21 and being opposite to the outer peripheral surface 21a of the axial part 21, and the whole or one part of the standing surface 40 has an inclined surface which is inclined to the same direction of a taper of the outer peripheral surface 21a of the axial part 21, and the inclined surface and the outer peripheral surface 21a of the axial part 21 are mutually opposite and close through a gap C with almost constant width.COPYRIGHT: (C)2011,JPO&INPIT【課題】ロータの回転時において貯液部の液体が大きな旋回流となることを回避し、もって前記旋回流に起因するミスト発生量のばらつきや騒音の発生を適切に抑制することが可能なミスト発生装置を提供する。【解決手段】ミスト発生装置MG1は、貯液部14の底面14aから上向きに突出し、かつロータ2の回転時に軸状部21の周囲において貯液部14の液体が旋回することを抑制可能に貯液部14の液体中に全体または一部が浸かるように設けられた旋回流抑制用の突出部4を備えており、この突出部4は、軸状部21の外周面21aに接近した位置において貯液部14の底面14aから上向きに起立して軸状部21の外周面21aに対向する起立面40を有し、この起立面40の全体または一部は、軸状部21の外周面21aのテーパと同方向に傾斜した傾斜面とされて、この傾斜面と軸状部21の外周面21aとは、略一定幅の隙間Cを介して互いに対向接近している。【選択図】 図1
