PURPOSE: An apparatus for supporting crank shaft of high speed precision former is provided to produce cold forged product having more accurate dimensions by minimizing elastic strain generated in the crank shaft due to load or impact. CONSTITUTION: The apparatus comprises a punch part(14) for forming a work; at least two punch shafts(20) for transmitting driving force to the punch part; a driving shaft(10) connected to the respective punch shafts so that the driving shaft transmits driving force to the punch shafts, and the center of the punch shafts is eccentric; a central shaft(30) positioned between the punch shafts so that the punch shafts are connected to each other, and the driving shaft corresponds to the center of the central shaft; and a supporting part(40) for preventing the punch shafts from being pushed or bent by load of the punch part, wherein the supporting part comprises a driving support(44) for supporting the driving shaft; and a central support(42) for supporting the central shaft.
