PROBLEM TO BE SOLVED: To prevent leakage of air while absorbing vibration of a blower. SOLUTION: A plurality (three pieces) of first rubber vibration isolators 214 support a motor 212, and a second rubber vibration isolator 215 prevents leakage of air through a clearance between a casing 213 and the motor 212 (a flange part 212b). Therefore, the first rubber vibration isolators 214 supporting the motor 212 need not be disposed all around the flange part 212b. Since the first rubber vibration isolators 214 support the motor 212 at three locations, it is possible to use the first rubber vibration isolators 214 having a coefficient of elasticity K1 capable of supporting the motor 212 while preventing the coefficient of elasticity K1 of the first rubber vibration isolators 214 from becoming excessively large. Thus, vibration of the motor 212 can effectively be absorbed while preventing leakage of air through the clearance of the casing 213 and the motor 212 (flange part 212b).
