PURPOSE:To provide easy assembly by putting a motor fitting frame between spiral cases and incorporating said combined members into a main case. CONSTITUTION:After a motor 20 and a gear motor 21 are fit to a motor fitting frame 17, a fan 21 is attached to the end of a shaft of the motor 20. A spiral case 16 and an intermidiate case 18 are then piled, with the fitting frame 17 between. A spiral case 19 is fit on the external face of the case 18 before the fan 22 is attached to the end of the shaft of the motor 20. The fans 21, 22 are completely the same with a difference in fitting direction. Finally, a whole body built up by piling up between as aforementioned is brought from an opening 30 of a main case 1b into the main case 1b for a completion at the side of the main case 1b. |
