    • PROBLEM TO BE SOLVED: To provide an optical device forming apparatus capable of forming a high precision optical device by regulating the axial deviation and the inclination between an upper die and a lower die.
      SOLUTION: Each of the upper die 20 and the lower die 30 has a nearly projecting shaped axial cross-section comprising an axial part 24, 34 and a table part 26, 36 respectively, wherein each of optical functional transfer surfaces 22, 32 is formed on a projecting end surface of the axial part and each of flange faces 28, 38 is formed around a projectingly provided part of the axial part of the table part. A first drum die is formed to guide the upper and lower movement of the upper die and the lower die. A second drum die 50 being in no contact with the first drum die is provided outside of the first drum die and is formed so that at the time of pressing at least one surface of the upper end surface or the lower end surface 52 is abutted on at least one of the upper die or the lower die to regulate the pressing limit distance of the upper die or the lower die, and at least one contact surface of the upper die or the lower die with the second drum die becomes a surface for regulating the inclination of the axial part.
