FAN DEVICE

PROBLEM TO BE SOLVED: To solve a problem that if a volume inside a fan device, which a circuit board storage part occupies, becomes large, the whole device is increased in size.SOLUTION: A fan device has a fan motor and a circuit board storage part for storing a plurality of circuit boards. The fan motor has an impeller rotating around a central axis and a wall face part surrounding the impeller from the outside in the radial direction. The plurality of circuit boards includes a first circuit board CB1 and a second circuit board CB2, which are connected opposite to each other. In a plane view from the direction in which the first circuit board and the second circuit board are opposed, the first circuit board has a first opposing area overlapping the second circuit board and a first non-opposing area not overlapping the second circuit board, and the second circuit board has a second opposing area overlapping the first circuit board and a second non-opposing area not overlapping the first circuit board. Electronic components or lead wires are disposed in the first non-opposing area and the second non-opposing area.SELECTED DRAWING: Figure 4 【課題】送風装置内部の基板収容部を占有する容積が大きくなると、装置全体が大型化し、これを解決する。【解決手段】送風装置にはファンモータと、複数の回路基板を収納する基板収納部とを有する。前記ファンモータは、中心軸を中心として回転するインペラと、前記インペラを径方向外側から囲む壁面部とを有する。前記複数の回路基板は、互いに対向して連結される第１回路基板ＣＢ１と第２回路基板ＣＢ２とを含む。前記第１回路基板と前記第２回路基板とが対向する方向からの平面視において、前記第１回路基板は、前記第２回路基板と重なる第１対向領域と、前記第２回路基板と重ならない第１非対向領域と、を有し、前記第２回路基板は、前記第１回路基板と重なる第２対向領域と、前記第１回路基板と重ならない第２非対向領域と、を有する。前記第１非対向領域及び前記第２非対向領域に、電子部品又はリード線が配置される。【選択図】図４
