PROBLEM TO BE SOLVED: To enhance the efficiency of a trimming step and a cauking step subsequent to successive forming by the utilization of a successive forming apparatus and to simply conduct the successive forming of a part such as a concave, which cannot be seen from the Z-axial direction as the pressing direction of a rod pressing member, unattainable by conventional successive forming. SOLUTION: A formed part after forming a work plate 1 into a three- dimensional shape has a concave 4, as shown in A, which cannot be seen from the Z-axial direction. As shown in B, the leading end of a pressing member is used as a swivel tool 20, and a multiaxial tiltable head 24 is used as a rod- shaped pressing member. While tilting the head part 24 to give a proper angle to the side of the concave 4, the inner wall 5, ceiling wall 6 and bottom wall 7 of the concave are subjected to successive forming for successive forming the concave 4. The other faces, which can be seen from the Z-axial direction, such as a side face 2 and a top part 3, are subjected to conventional successive forming in such a manner that the axis of the rod-shaped pressing member 10 or the head 24 is made to be in parallel with the Z-axial direction.
