Claims

[Claims for Utility Model Registration] (1) A bearing held by a support leg at the center of an opening on one end side of a cylinder forming an air passage; a support shaft accommodated in a slidable manner; a blade fixed to one end of the support shaft to close an opening at one end of the cylindrical body; and an elastic member biasing the support shaft in a direction in which the blade closes the opening. , an air damper that applies an elastic force to the blade that is weaker than and counteracting the bias of the elastic member, a drive motor provided outside the air passage formed by the cylinder, and a connection that connects the drive motor and the support shaft. A cable, a pulley on which the connecting cable is hung, and a pulley for changing the direction of the connecting cable, and the support shaft is slid through the connecting cable by rotation of the drive motor against the bias of the elastic member. A damper device characterized in that the blade is separated from an opening of a cylindrical body to open the opening. (2) A bearing held by a support leg at the center of the opening on one end side of the cylinder forming the air passage; a support shaft, a blade fixed to one end of the support shaft and closing the opening on the one end side of the cylindrical body, an elastic member biasing the support shaft in a direction in which the blade closes, and the elastic member attached to the blade. A spring that applies a spring force that is weaker than the bias and counteracts the bias, a drive motor provided outside the air passage formed by the cylinder, a connecting cable connecting the driving motor and the support shaft, and a connecting cable to which the connecting cable is hung. and a pulley for changing the direction of the connecting cable, and by the rotation of the drive motor, the support shaft is slid through the connecting cable against the bias of the elastic member, and the blade is moved into the opening of the cylinder. A damper device characterized in that the damper device is configured to open the opening by moving away from the damper device.
