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 flow volume reaches a set air flow volume. CONSTITUTION:A memory portion 23 disposed within a microcomputer 22 stores preset positions of a vertically deflecting vane 1, and horizontally deflecting vanes 5a and 5b. An air flow volume sensor 21 detects the volume of an air flow blown off through a blower-off port. In dynamic signal generating means 24, vertically deflecting vane 1 and horizontally deflecting vanes 5a and 5b are driven so that a blast from the blow-off port is branched downwardly 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 24 emits signals to rotate the vertically and horizontally deflecting vanes 5a and 5b to set positions stored in the memory portion 23, to a middle motor 3, a left motor 9a and right motor 9b.
