In this report the force acting normal to the die surface in rolling a thread by the flat die type machine was calculated according to YAMAMOTO'S theory on the thread rolling force, and the results of calculation were compared with REICHEL'S experiment. YAMAMOTO derived the general equation on the thread rolling force according to his own theory. The solutions of this equation for the case of the oil pressure type machine, in which the screw stock is revolved over 10 times until the thread is formed completely, coincide to his experimental results. But his equation must be modified somewhat in the case of the flat die type machine, in which the screw stock is revolved 5 to 6 times at most. After this modification, the equation was solved for the same example as REICHEL'S experiment. This solution was found out to be a good approximation to REICHEL'S experimental results.
