PURPOSE:To improve a motor fixing job efficiency and lower a draft resistance, by fixing two motors independently driving respective inside and outside fans on a single motor mounting leg. CONSTITUTION:A spacer 9 is tightly placed on opposite sides of through-hole 8 defined in a mounting leg 1, and inside and outside motors 4a, 4b are respectively urged on the spacer 9 for tightly pressing it against the mounting leg 1. A fixing screw is inserted into the hole 6 of mounting leg 5 from the direction of outside motor 4a with the above state maintained, and two motors are positively fixed in place by tightening the screw into the hole 6 of leg 5 for inside motor 4b. Inside and outside motors 4a, 4b are thus simultaneously and positively fixed on the mounting leg 1, whereby improving a motor fixing job efficiency with less number of steps. Moreover, less mounting space requirement contributes to lower a draft resistance. |
