A wind direction alteration device for use in an integral type air conditioning apparatus in which the diameter of a connecting shaft of a blade extending through an opening formed in a connecting rod is greater than that of the shaft above and below the opening. The opening of the connecting rod is elongated and constricted in the center thereof. Three or more projections are extending into the opening through which the connecting shaft penetrates. A portion, holding the connecting rod, formed on a shaft of a wind direction alteration motor is disposed beyond a vertical movable range of the connecting rod. A portion, of the connecting rod, which is in contact with the portion of the shaft holding the connecting rod is inclined. A rib is formed on the inner surface of the elongated opening, of the connecting rod, through which the shaft of the wind direction alteration motor penetrates such that the rib is parallel with the direction in which the elongated opening is formed.
