Claims

[Scope of utility model registration request]

a bearing held by a support leg at the center of an opening on one end side of the cylinder forming an air passage, and a support shaft supported by the bearing and housed in the cylinder so as to be able to slide in the direction of the center line. , a blade fixed to one end of the support shaft and closing the opening at one end of the cylinder; an elastic member biasing the support shaft in a direction in which the blade closes; and an air passage outside the cylinder. a drive motor provided on the drive motor, a connecting cable connecting the driving motor and the support shaft, hanging the connecting cable,
A pulley for changing the direction of the connecting cable is provided, and the support shaft is slid through the connecting cable by rotation of the drive motor against the bias of the elastic member, and the blade is separated from the opening of the cylinder. The drive motor is configured to open the opening when the clutch coil is turned on and off, and the drive motor includes a motor pulley that winds up the connecting cable through a clutch that is connected and disconnected when power is turned on and off to the clutch coil, and a motor pulley that winds up the connecting cable through a clutch that is connected and disconnected when power is turned on and off to the clutch coil. A switch is provided in parallel with the clutch coil that cuts off the power, and when the motor pulley rotates to a predetermined position, the switch opens and the clutch coil continues to be energized even when rotation is stopped. Features a damper device.
