The present invention was devised to solve these problems, and its purpose is to open and close branched ducts, so the structure is simple, and the motor only rotates in one direction to move the damper blades left and right. The object of the present invention is to provide a branch duct that swings to open and close, and as a technical means for that purpose, the present invention uses a motor to drive a damper blade that is rotatably supported inside a duct that branches in three directions to open and close the duct. In a branch duct designed to open and close in two directions, a unidirectional rotating motor is used as the motor, and a crank attached to the rotating shaft of the motor slides into a guide groove formed in the damper blade. A movably locked structure was adopted.

Therefore, in the branch duct of the present invention, a sliding mechanism is used in which two dead centers are created when a crank attached to a unidirectional motor rotates and slides the guide groove of the rotatably supported damper blade. As the crank rotates, the damper blade swings around the shaft support each time the crank passes the dead center, so this is controlled by a limit switch to open or close any of the ducts in two directions. do.
