Claims

[Scope of utility model registration request]

A support shaft is provided inside the cylinder forming the air passage so as to be able to slide in the direction of the center line, and the support shaft has a blade at one end that closes an opening at one end of the cylinder, and a blade on the outer periphery that closes the opening at one end of the cylinder. An elastic member is provided for urging the blade toward the closing side, a drive motor is provided outside the air passage formed by the cylindrical body, and the drive motor and the support shaft are connected by a connecting cable hung on a pulley. , the supporting shaft is slid through the connecting rope against the bias of the elastic member by the rotation of the drive motor, and the blade is separated from the opening of the cylinder body to open the opening. At the same time, the inner cylindrical portion of the support shaft and the elastic member were covered with a cylindrical case, and a guide plate for regulating the rotation of the support shaft was mounted in the case against a rib formed on the inner wall of the case. A damper device characterized by:
