The present invention relates to a door buffer. The door buffer comprises: a magnetic force generating unit formed on one side of a door to generate a magnetic force; and an eddy current generating unit which is located in a door frame to correspond to the magnet force generating unit and generates an eddy current according to the approach of the magnetic force generating unit. The magnetic force generating unit has a permanent magnet. The eddy current generating unit is made of a copper plate with a predetermined thickness and has an iron core in the center thereof. Therefore, the door buffer can enhance an effect of preventing a door from closing with repulsive power caused by an eddy current by directly attaching a magnet to sides of a door and a door frame and can reduce a trouble because of a rigid installation structure. Also, the door buffer can be easily applied to an automatic sliding door, thereby preventing shock or noise generated when a door is closed and preventing a user from being trapped in a door due to the carelessness of the user. |
