Abstract
PURPOSE: To reduce the manufacturing cost of a safety guard by forming a large number of cutout arcuate apertures radially extending in a sheet material, leaving a center disc portion therein, and then carrying out extrusion with using an extrusion die, and to maintain a regular quality by eliminating welded portions from the safety guard so as to prevent generation of trembling sounds caused by vibration.
CONSTITUTION: A safety guard 7a is composed of louvers 7b which form, as a whole, a generally convex shape but define an inverted concave coned shaoe in the center portion of the safety guard 7a. Moreover, since the safety guard 7a has no welded portion, there is no problem of leaving unwelded portions. Therefore, trembling sounds due to vibration are hard to generate during operation of the blower 4. Further, with this arrangement which can be obtained in such a manner that a large number of arcuate apertures 7d radially extending are formed in a sheet material, leaving a center disc portion therein, and then extrusion is carried out with using an extrusion die 10, the safety guard can be manufactured through less manufacturing proccess steps at reasonable costs.
