Claims

[Scope of Claim for Utility Model Registration] A door wheel mechanism provided at the top of the door on a guide rail fixed to an upper frame forming a part of the opening frame runs by a drive device to open and close the door, and The soundproof automatic door is equipped with a presser device that is provided with a gasket at a position facing the door around the opening of the opening frame and presses the door against the gasket when the door is closed, wherein the presser device is configured to prevent external noise from entering the door. A speed reducer driven by a motor that can be rotated in forward and backward directions in response to a signal, a cam eccentrically attached to the rotating shaft on the output side of the speed reducer, and the cam at the maximum and minimum eccentric distance positions with respect to the door. A soundproof automatic door comprising: a stopper that regulates the rotation of a rotating shaft;
