PURPOSE:To permit the attaching of a dust-proof net to condensers having different sizes by cutting the net so as to have a predetermined size and pinching the rims of the net by adaptor members. CONSTITUTION:When the sheet body 9A of an adaptor member 9, which is provided with a protuberance 13, is pivoted about a hinge section 11, the protuberance is fitted into the recessed section 14 of another plate body 9B. Accordingly, the rim of a net 10 is put on either one of the plate body 9A and, thereafter, the other plate body 9B is pivoted whereby the protuberance 13 is fitted into the recessed section 14 and the net 10 can be pinched by both plate bodies 9A, 9B. On the other hand, the net 10 can be cut so as to have an arbitrary side. According to this method, a dust-proof net can be prepared by cutting the net 10 so as to have a predetermined size and the rims of the net 10 are pinched between the adaptor members 9 whereby the net 10 can be attached to condensers 5 having a plurality of kinds of sizes by only preparing the adaptor members 9 having a size adaptable to the height or the width of the condenser 5. Further, the dust-proof net can be attached to the condenser by only forcing the protuberances 15 between the pipes 12, 12 of the condenser 5. |
