PURPOSE: A forging dies for forming output rod is provided which prevents damage of dies pin by impact applied from pressing punch and enables the preformed hole to be formed accurately at the same time when forming a preformed hole on the output rod. CONSTITUTION: The forging dies(10) for forming output rod is characterized in that a dies supporting member(18) in the center of which a guide hole(18a) is formed so that an output rod resting groove(18b) having a certain depth is formed on the front end of the guide hole, and on the other end of the guide hole of which a key guidance groove(18c) having a certain depth is formed is inserted onto the inner diameter of a dies ring fixing member(12), a stripper(17) is installed in the guide hole of the dies supporting member in such a way that an insertion part(17a) having a certain diameter for supporting an end of the central shaft of the output rod (B) is formed on the stripper, a long hole(17b) corresponding to the insertion part is formed on the stripper in a length direction of the insertion part, a catching projection(17c) is formed on one side of the insertion part, and a hollow(17d) is formed in the inner center of the stripper, a dies extrusion pin(19) for forming a preformed hole on the central shaft of the output rod with being supported to an end of the dies pin during hitting of a pressing punch (A) is inserted into the hollow of the stripper, and a stopper pin(19-1) for guiding the dies extrusion pin from the section of the key guidance groove of the dies supporting member is vertically penetrated into a certain position of the dies extrusion pin.
