PURPOSE: To provide an adjusting apparatus of a folding jaw mechanism inexpensively constituted of a small number of parts and characterized by having only a small inertia mass when controlling the folding jaw mechanism. CONSTITUTION: A cylinder body 2 is rotatably arranged on a cylinder shaft, an unopening jaw part 8 of a folding jaw mechanism is fixed to the cylinder body 2, and a transmission mechanism is connected to a support 9 to rotate the cylinder body 2. Thus, the transmission mechanism acts, and rotary motion is imparted to the support 9 so that the jaw part 8 moves in the direction for separating from an opening/closing folding jaw plate 11 or in the approaching direction, the support 9 rotates the folding jaw plate 11 in the opposite direction to motion of the jaw part 8, and a roller lever having a roller is fixed to a spindle 10. |
