Abstract
A support structure for a drive source such as a motor of the blower is disclosed in which the generation of noise caused by the vibration of the motor is suppressed. The flange of a support member has a low-stiffness portion having a thickness smaller than a high-stiffness portion of the same flange. The low-stiffness portion is thus vibrated more easily than the high-stiffness portion. When the motor vibrates, therefore, the vibration rate of the low-stiffness portion increases beyond that of the high-stiffness portion, so that the low-stiffness portion vibrates considerably. The motor vibration is thus absorbed by the flange (support member) and the transmission of the motor vibration to a casing can be suppressed. As a result, the area of the sound source of the blower is decreased as a whole, thereby making it possible to suppress the generation of noise caused by the vibration of the motor.
