Abstract
To enhance a cooling efficiency of a cooling device using an axial fan motor, air rectification blades 1 are provided with hooks 1e engaged with a flange 2b of an axial fan motor 2 for fixing the air rectification blades 1 to the axial fan motor 2. The attachment/detachment of the air rectification blades 1 to the axial fan motor 2 is performed in a so-called one-touch manner without using any tool or jig by flexing the hooks 1e. It is possible to obtain the axial fan motor provided with the air rectification blades having optimum characteristics by attaching/detaching the air rectification blades 1 in the one-touch manner in a situation where the air rectification blades 1 are needed later for the axial fan motor not provided with any air rectification blades or the characteristics of the air rectification blades 1 are to be changed.
