Abstract

PURPOSE: To cheaply manufacture a guard with stable quality by a method wherein a louver radially slitted from its center to outer periphery, the whole part of which is formed so as to cover the outside of the blower in protruded shape, is adopted as the guard of the blower.
CONSTITUTION: A base 7 is made in its plane state to have a large number of slits (d), with the shape of a circular arc when projected on a plane, radiating from the periphery of a central circular plane part 7c to the outer circular periphery. When the base 7 is pressed up at its center part with a forming die 10 at the state of its outer circular periphery being clamped between a lower die 8 and an upper die 9, the central circular plane part 7c is rotatingly pressed up so as to make a louver 7b uprightly open and then a guard 7a is formed. After that, the base 7 is completed by bending a riser 7f. Because subject guard 7a for the protection of the blower 4 is manufactured as mentioned above and the whole radial louver 7b is formed in protruded shape without any welds or the like, the guard 7a can be cheaply manufactured with a numbers of operations as stable products.
