PROBLEM TO BE SOLVED: To correctly decide a position of a piece to a lower die body when a die is assembled at a normal temperature and to firmly fix the position by inserting a taper cotter which dissolves a gap between the piece and the lower die body between these members. SOLUTION: A piece 22 having small V grooves 24 and large V grooves 26 is filled into a recessed part 20 formed in the front end part of a lower die main body 18 in a lower die. A fiber hole of a ferule is formed with a core pin and also a guide pin hole of the ferule is formed with a guide hole forming pin respectively by inserting the core pin into the small V groove 24, also by inserting the guide hole forming pin into the large V groove 26 and by forming them with resin. A taper cotter 28 for dissolving a gap between these members is inserted between the piece 22 and the lower die main body 18. Further, the generation of the gap between respective members generating in temperature rising is prevented by interposing a thin rectangular spacer 42 between the piece 22 and the taper cotter 28 or between the piece 22 and the lower die main body 18.
