Zusammenfassung:	PROBLEM TO BE SOLVED: To solve a problem wherein when a mounting member used for mounting a motor to a motor base has a small contact area with the motor and motor base, since release of heat generated in the motor to the motor base is deteriorated, the temperature of a motor bearing is raised, leading to decline in the service life of the motor bearing. SOLUTION: An air blower portion comprising an air blowing fan connected to the motor by a motor shaft, a bell mouth having a suction port formed thereon and a scroll formed to surround the periphery of the air blowing fan and the motor to which the air blowing fan is connected are mounted to the motor base by the mounting member. In the mounting member, a contact area of a stator core of the motor with the mounting member and a contact area of the mounting member with the motor base are set larger than that of a bracket to which the motor bearing of the motor is inserted with the stator core.
