PROBLEM TO BE SOLVED: To provide a device for adjusting a kneading degree which can synchronously rotate two gate rods mutually in reverse directions by utilizing an arm, a feeding screw body, a motor or an arm, a gear and a cylinder, and can stop the gate rods at any position to retain that position. SOLUTION: The constitution of the kneading degree adjusting device is capable of rotating respective gate rods (3, 3a) mutually in the reverse directions by utilizing the assembly comprising arms (10, 10a) fixed to the gate rods (3, 3a), a feeding screw body (11), nuts (14, 14a) screwed into respective screw parts (11a, 11b) of the feeding screw body (11), and a driving body (12) for driving the feeding screw body (11), or the assembly comprising the gears (30, 30a), the arm (10a), the rod (32) and the cylinder (33) connected to the gate rods (3, 3a). |
