To provide a forging apparatus which has a simple structure and high flexibility, and can facilitate process designing.
The apparatus includes a forging tool 5 which presses a material M and deforms the material M into a designated three-dimensional shape. The forging tool 5 has side face tools 50a and 50b arranged around the material M. The side face tools 50a and 50b are composed of movable pieces 51a-55a and 51b-55b which are arranged from one end side to the other end side of the material M and can push the material M individually and independently. The forging apparatus can succeedingly push the material M with the movable pieces from one end side to the other end side. Furthermore, a tool supporting means is prepared which holds the material M with the movable pieces 51a and 51b while maintaining relative positions of the movable piece 51a, the movable piece 51b and the material M, when the movable piece 51b, which is neighboring to the movable piece 51a pushed into the material M ahead of the 51b, is pushed into the material M.
