Air blowing device and manufacturing method thereof

In the blower device, a mounting member is mounted across the radially outer surfaces of a first axial fan and a second axial fan connected in series. A part of the third connection portion of the mounting member is connected to the first connection portion of the first axial fan. The other part is connected with the second connecting part of the second axial fan. An extension portion of the attachment member extends in the axial direction from the third connection portion and is disposed at a radially outer end portion of at least one of the first cylinder portion and the second cylinder portion. The extension portion surrounds at least one of the first lead and the second lead together with a radial outer end portion of at least one of the first cylinder portion and the second cylinder portion. 在送风装置中，跨在串联连接的第一轴流风扇及第二轴流风扇的径向外侧面安装安装部件。安装部件的第三连结部的一部分与第一轴流风扇的第一连结部连结。另一部分与第二轴流风扇的第二连结部连结。安装部件的延伸部从第三连结部沿轴向延伸，并配置在第一筒部和第二筒部的至少某一方的径向外端部。延伸部与第一筒部和第二筒部的至少某一方的径向外端部一起包围第一引线和第二引线的至少某一方。
