Abstract
The present invention relates to a prevention device that is installed on a door frame of an opening/closing door to prevent sudden closing of the opening/closing door, and more particularly, to an impact noise prevention device for an opening/closing door which is configured to install wings on one side of a hinge fixed to the door frame, allows the wings to rotate around the hinge by the force of the wind passing between the opening/closing door and the door frame, i.e. the wind force, thereby reducing the impact and noise caused by the sudden closing of the opening/closing door, and is installed in the door frame to conveniently perform its installment and removal.
