DIE SET FOR PRESS DIE

PROBLEM TO BE SOLVED: To provide a die set for a press die preventing the generation of a linear flaw and seizure and facilitating the regulation of positioning without degrading dimensional precision. SOLUTION: A running plane 121 or the like in parallel with the center axis and rectangular to the radius are formed in the main side surface of a guide post 1. Plate-like sliding members 21 made from a carbon fiber dispersed resin or carbon fiber dispersed porous ceramic are installed to the inner surface of the guide bush 4. When the guide post 1 is inserted and pierced into the hollow part of the guide bush 4, the running plate 121 or the like of the post guide 1 and the sliding surface of sliding members 21 are closely brought into contact, these center axes are aligned, and the guide post is slid in parallel with the common center axis and moved linearly.
