Claims

[Claims for Utility Model Registration] A plurality of blades that are rotatably provided in parallel to each other within an opening of a housing from which a predetermined amount of air is to be blown are interlocked by a connecting member that connects them. At the same time, the drive mechanism automatically makes the swing movement,
In an automatic wind direction adjustment device configured to blow wind in a predetermined direction, the pivot shaft of the blade or the connecting member is connected to an arm member that is linearly reciprocated in the longitudinal force direction by the drive mechanism. , are connected via a clutch mechanism that realizes motion transmission under a predetermined frictional force, and automatically swing the plurality of blades within the operating stroke range of the drive mechanism of the arm member; Movement that is held by a predetermined stationary member with a force greater than the force received during rotation of the blade, which has a retaining portion that engages with at least one of the blades and restricts both ends of the swinging movement of the blade. A swing center changing means capable of changing the swing center is provided, and by moving the swing center changing means to a predetermined position, the engagement position of the retaining part with respect to the blade is changed, and the movement regulated by the engagement part. A swing center changing mechanism in an automatic wind direction adjustment device, characterized in that the end of the swing movement range is changed by changing the end of the swing motion range.
