PURPOSE:To prevent dewing on and around the motor of a blower, by integrally providing a spiral case with a seat for holding the motor. CONSTITUTION:A holder, on which the peripheral part of a motor 3 is put in pressure contact to hold the motor, is integrally formed on the spiral-center part of a spiral case 7, which is located on the side of exhaust. A thick part is provided on the bottom of a spiral case 6 on the side of suction so that a sucked air passage X and a discharged air passage Y are divided from each other. Since a seat for holding the motor 3 is provided directly on the spiral case, dewing is prevented. |
