PROBLEM TO BE SOLVED: To provide a die of a forging machine which can rapidly and economi cally produce a metal parts by reliably advancing/retracing the die. SOLUTION: A pair of die members 33, 33 are formed of a three-dimensional body having a contour shape comprising two parallel surfaces and two inclined surfaces which are orthogonal to the parallel surfaces and narrower in the space therebetween to the depth, and split into two by the section orthogonal the two parallel surfaces, triangular guide projections 49, 49 are provided in a center of two parallel surfaces 31a, 31a constituting an inner surface of a space of a die holder 31 storing the die members 33, 33, and guide recesses 33b...33b to be fitted to the guide projections 49, 49 are provided on surfaces 33a...33a facing the two parallel surfaces 31a, 31a of the die holder 31 of the die members 33, 33.
