<P>PROBLEM TO BE SOLVED: To provide an air conditioner capable of preventing scattering of abrasion powder of a revolving belt and a pulley into an air-conditioning object room. <P>SOLUTION: This air conditioner is provided by forming a ventilation passage B communicating a suction port 9 with a blowout port 10 in a body casing A, and is formed by arranging a heat exchanger 8, a fan 6, a fan side pulley 3 installed on a rotary shaft 20 of the fan 6, a motor side pulley 2 installed on a rotational driving shaft 19 of a motor 1, and the revolving belt 4 wound around between the fan side pulley 3 and the motor side pulley 2, in the ventilation passage B. The air conditioner is formed by arranging the fan 6 on the downstream side in the ventilation direction more than the fan side pulley 3, and is constituted so as to be isolated from the ventilation passage B by covering the motor side pulley 2, the fan side pulley 3 and the revolving belt 4 with a cover member 11. <P>COPYRIGHT: (C)2009,JPO&INPIT |
