SLIDING DOOR DEVICE FOR AIR CONDITIONER

PROBLEM TO BE SOLVED: To attain thinning and weight reduction without causing hindrance to seating performance, sliding performance and air pressure withstanding performance of a door body. SOLUTION: A door body 2 has a protruding part 11 bulging onto the windward side. This protruding part 11 is formed in arc shape within a plane orthogonal to a sliding direction so as to have a form of functioning as an arch dam to air pressure, presenting arc shape bulging onto the windward side on the whole from the upper edge to the lower edge. When drive mechanism 4 is arranged on the rearward side of the door body 2, the drive mechanism 4 supports the door body 2 receiving air pressure, on the rear side so as to function as a shape inversion preventing member for the door body 2. When the drive mechanism 4 is arranged on the windward side of the door body 2, the space of the door body 2 can be used as space for arranging functional parts other than the drive mechanism. In case of forming the door body 2 of the same material as a case 3, there is no need to classify the door body 2 and the case 3 at the time of recycling a spent air conditioner.
