A doorknob cover comprise a hollow cylindrical body and an element which is capable of attracting magnetically or being attracted magnetically. The cylindrical body is provided in one side with an elastic opening, and in other side with the element. The doorknob cover is fitted over the doorknob via the elastic opening. As the door is swiveled toward a wall, the doorknob is arrested by a magnetic seat of the wall due to the magnetic attraction between the element of the doorknob and the magnetic seat of the wall.
