Abstract

PURPOSE: To facilitate the production of wing-shaped blade of blower and the modification of the blade shape by constituting the back plate and front edge portion of the blade from hard material on which the body side portion made of soft material is fixedly overlaid.
CONSTITUTION: A back plate 1 and cylindrical front edge portion 10 of blade are made of an unitary hard material plate like steel plate, vinyl chloride plate, etc. and overlaid fixedly by a body side portion 2 of soft material like rubber. Since the body side portion 2 is made of soft material, it can be mounted even if the shape of blade varies and changed in its length and width easily by cutting. Thus, flow property of blower can be varied easily by changing the shape of blade. Also, by making the body side portion 2 shroter than the back plate 1 and leaving only a portion thereof on the outlet part of the blade to be transformed, the outlet angle of blade can be changed to vary air flow and pressure characteristics.
