PURPOSE:To provide space heating with uniform temp. by installing two wind direction changing plates in such a way that a motor-driven rotating body guides the eccentric ends of rotating shafts of adjacent two wind direction changing plates into guide paths of the rotating body to swing the plates as the rotating shafts are centered and the two plates are swung simultaneously in the upper and lower directions. CONSTITUTION:When air conditioning operation is started, motors 22 placed at corner parts 21a, 21b are driven to revolve rotating bodies 24a, 24b. Thereby, each eccentric end of rotating shafts 26a, 26b and 26c, 26d in adjacent wind direction changing plates 4a, 4b and 4c, 4d respectively is guided by guide path 25 and is swung as the shafts 26a, 26b and 26c, 26d are centered. Thereby, the two plates 4a, 4b and 4c, 4d are swung in the upper and lower directions. As a result, comfortable air conditioning effect with uniform air temp. is able to be obtained.
