To provide an appropriate air flow control structure in which application to various structural bodies of an air blowing section for controlling air flow is enabled, pressure loss is reduced, noise is restrained, and dew condensation at cold blast is hard to generate.

In the air blowing section such as a fan section and an air passage in which the air flow passes, in various blowers for example, an edge part of an air flow control structural body which controls the passing air flow is flexibly formed of soft synthetic resin member or the like for example. By elastically deforming the edge part freely in accordance with flow of air and change of pressure, separation of the flow and wind noise are restrained.
