To enable the adjustment of the height of a lower punch on the lower base side.

In the forming apparatus mounting an upper punch 50 on the upper base 48 side of a press, mounting a lower punch 4 on the lower base 49 side, and fixing a die 2 between the upper punch 50 and the lower punch 4, the lower punch 4 is mounted on the lower base 49 side through a height adjustment mechanism 10. The height adjustment mechanism 10 is composed of an adjust screw 25 and a punch holder 11. The punch holder 11 consists of a punch holder lower half part 12 to be freely rotatably fastened to the adjust screw 25 and a punch holder upper half part 16 to be freely rotatably connected to the punch holder lower half part 12 through a coupling 21. By adjusting the degree of the screwing down of the punch holder lower half part 12 to the adjust screw 25, the height of the lower punch 4 positioning in the upper part of the punch holder upper half part 16 can be adjusted.
