Abstract

PURPOSE: To make longer the interval of maintenance requiring filter replacement and contrive the reduction of the deformation of a filter accompanied by the rotation of a fan by shaping into a saw-toothed form the cross section of a filter cover for protecting a fan provided at the end face of an electronic machine.
CONSTITUTION: The cross section of a filter cover 1 for protecting a fan provided at the end face of an electronic machine is shaped into a sawtoothed form. This filter cover 1 is manufactured by a method wherein two jigs 3 and 3', each having a plurality of projection parts 3a formed at predetermined intervals, are set facing each other with a plurality of the projecting parts 3a in engagement with one another and the two jigs 3 and 3' are pressed with the filter cover 1 interposed therebetween from the two sides thereof. As a result, the interval of the maintenance requiring filter replacement can be made as long as possible and the deformation of the filter accompanied by the rotation of the fan can also be reduced.
