PROBLEM TO BE SOLVED: To provide a workpiece supporting mechanism for two-die form rolling which can perform form rolling of a tubular workpiece such as a small-diameter pipe or thin-walled pipe at low costs without a fall or breakage of the workpiece. SOLUTION: The invented workpiece supporting mechanism for two-die form rolling supports the tubular workpiece W and performs form rolling by means of a pair of reciprocally confronting round dies 8 and 9. The workpiece supporting mechanism is equipped with a core bar 1 which supports the tubular workpiece W which is interposed over the front part of the core bar 1, a holder 2 which fixes the rear part of the core bar 1, and a rotary supporting means 3 which supports the holder 2 so as to be free to rotate.
