Abstract

PURPOSE: To obtain this ventilating device that lowers noises and abnormal noises are little in a shape that does not enlarge the dimensions of a main body or need not complicate working forms.
CONSTITUTION: In this ventilating device that the inside of a main body case 1 is provided with a motor 5 and a blade 6 driven by means of the motor 5, and sucks polluted air from a suction port of a fan cover 7 and exhausts it through a duct connecting portion material 10 from an exhaust port of the main body case 1, a motor hole with return larger than an outer circumference of the motor 5 is mounted to an upper surface of the main body case 1 while conforming the hole with the center of the motor 5, and a packing 12 with elasticity is installed between the outer circumference of the motor and the motor hole. Thus, the height of the main body case 1 can be lowered while the vibration of the motor 5 and the resonance of the main body case 1 can be prevented because a housing of the main body case 1 further covering a house of the motor is eliminated, and noises can be lessened.
