PURPOSE:To make it possible to shorten a space heating operation time, to carry out an efficient space heating operation and to improve the comfortableness of a living space by setting a desired air flow direction position and automatically switching the air flow direction to the desired air flow direction position when the blow-off air vol. reaches a set air flow vol. CONSTITUTION:A memory portion 23 disposed within a microcomputer 22 stores preset positions of a vertically deflecting vane 1 and horizontally deflecting vanes 4a and 4b. An air flow vol. sensor 21 detects the vol. of an air flow blown off through a blow-off port. In drive signal generating means 24 the vertically deflecting vane 1 and horizontally deflecting vanes 5a and 5b are driven so that a blast through a blow-off port is branched horizontally or upwardly right-and-left. When the air flow vol. detected by the air flow vol. sensor 21 has become equal to a set air flow vol., the means 21 emits signals to rotate the vertically and horizontally deflecting vanes 5a and 5b to the set positions, to a middle motor 3, a left motor 9a and a right motor 9b.
