Summary:PURPOSE: An apparatus for reducing the opening force of a hinged door is provided to easily open a hinged door using elastic energy stored when the hinged door is opened. CONSTITUTION: An apparatus for reducing the opening force of a hinged door comprises a storage unit, a door opening unit(50), a return unit(60), and a restriction unit(70). The storage unit stores elastic energy when a hinged door(4) is opened. The door opening unit is installed in one side of a door frame and reduces the opening force of the hinged door when the hinged door is opened. The return unit is installed in the hinged door and stores elastic energy to the storage unit by rotating the door opening unit clockwise. The restriction unit is installed in the door frame to restrict the rotation of the door opening unit.
