Abstract: A hinged door fixing apparatus comprises a fixed part and a holder part. The fixed part is fixed on a wall such that, in order to prevent the doorknob or edge portion of a hinged door from bumping directly against the wall in the process of opening the hinged door, a buffer member having a buffer ball coupled to the end thereof, which is mounted to the hinged door, comes into contact with the fixed part in the opening process. The holder part is installed in the fixed part and instantaneously holds the buffer ball through elasticity when the buffer member bumps against the fixed part.
