2. Description of the Related Art A wind direction changing device mounted on a decorative panel or the like of an air conditioner is disclosed, for example, in Japanese Patent Application Laid-Open No. 63-306333. A wind direction changing plate arranged to perform a swinging motion, a motor for driving the wind direction plate, a crank mounted on a rotating shaft of the motor, and an operating groove into which the shaft of the crank is inserted. And a connecting member for converting the rotational motion of the shaft into a swinging motion.

[0003]

In the wind direction changing device, since the operating groove of the connecting member is formed in a straight line,
When the rotation axis of the motor is moved by a predetermined angle, the crank shaft inserted into the operation groove moves in a direction substantially along the operation groove, and the crank shaft moves in a direction crossing the operation groove. Since the swing angle of the wind direction changing plate is different, it was not possible to swing the wind direction changing plate by a predetermined angle by moving the rotation axis of the motor by a predetermined angle. Further, when the rotating shaft of the motor is rotated at a constant speed, the swing of the wind direction changing plate may be fast or slow, and the wind direction changing plate cannot be swung at a constant speed.

The present invention provides a wind direction changing device in which a swing angle of a wind direction changing plate is set in proportion to a rotation angle of a driving motor.
