A die cushion apparatus of a press machine comprising an information acquiring device (23L, 23R) which acquires information regarding inclination of a cushion pad in a duration of die cushion force control, characterized in that in operation the cushion pad is held on standby in parallel with lower faces of dies mounted to a slide of the press machine by carrying out an adjustment, based on the information acquired from the information acquiring device, the die cushion apparatus further comprising: multiple cushion pad raising and lowering devices (4L, 4R) which in operation raise and lower a cushion pad by separately-controllable multiple driving shafts (4La, 4Ra); a die cushion position instructing unit which in operation outputs position instruction values for instructing positions in a raising and lowering direction of the cushion pad, the die cushion position instructing unit including standby position instruction values for at least holding the cushion pad at a standby position, and outputting the standby position instruction values after knocking out a product; multiple die cushion position detecting devices (23L, 23R) which in operation detect the position of the cushion pad corresponding to the position for each driving shaft (4La, 4Ra) of the multiple cushion pad raising and lowering devices (4L, 4R), and output position detected values indicating the detected positions; an offset adjusting device (321L, 321R) which in operation offsets one or more of the multiple position detected values outputted from the multiple die cushion position detecting devices (23L, 23R) by a previously-set offset value, and outputs this value; and a controlling device which in operation separately controls the multiple cushion pad raising and lowering devices (4L, 4R) based on the position instruction values outputted from the die cushion position instructing unit, and on the multiple position detected values outputted from the multiple die cushion position detecting devices (23L, 23R), and moves the cushion pad to the standby position based on the standby position instruction values outputted from the die cushion position instructing unit after knocking out the product, wherein the offset value is adjusted based on the information acquired from the information acquiring device (23L, 23R) to allow the cushion pad to be held on standby in parallel with the lower faces of dies mounted to the slide of the press machine. multiple cushion pad raising and lowering devices (4L, 4R) which in operation raise and lower a cushion pad by separately-controllable multiple driving shafts (4La, 4Ra); a die cushion position instructing unit which in operation outputs position instruction values for instructing positions in a raising and lowering direction of the cushion pad, the die cushion position instructing unit including standby position instruction values for at least holding the cushion pad at a standby position, and outputting the standby position instruction values after knocking out a product; multiple die cushion position detecting devices (23L, 23R) which in operation detect the position of the cushion pad corresponding to the position for each driving shaft (4La, 4Ra) of the multiple cushion pad raising and lowering devices (4L, 4R), and output position detected values indicating the detected positions; an offset adjusting device (321L, 321R) which in operation offsets one or more of the multiple position detected values outputted from the multiple die cushion position detecting devices (23L, 23R) by a previously-set offset value, and outputs this value; and a controlling device which in operation separately controls the multiple cushion pad raising and lowering devices (4L, 4R) based on the position instruction values outputted from the die cushion position instructing unit, and on the multiple position detected values outputted from the multiple die cushion position detecting devices (23L, 23R), and moves the cushion pad to the standby position based on the standby position instruction values outputted from the die cushion position instructing unit after knocking out the product, wherein the offset value is adjusted based on the information acquired from the information acquiring device (23L, 23R) to allow the cushion pad to be held on standby in parallel with the lower faces of dies mounted to the slide of the press machine.
