摘要： A channel is sufficiently limited, and thereby a sufficient range for adjusting the degree of kneading is ensured. Two screws is rotatable around first axes of rotation. A pair of gate rods 5 that sandwich two screws 4 and that are opposite to each other is provided. The gate rods are rotatable around second axes of rotation A2. Each of the pair of gate rods has two recess parts 9, and recess parts 9 that are opposite to each other form respective spaces through which the two screws penetrate. Each of the pair of gate rods 5 has first contact surface 21 that comes into surface contact with screw 4 when gate rod 5 is rotated to a minimum degree-of-opening position where an area of a channel that is formed between gate rod 5 and screw 4 is minimized, large diameter part 24, 27 that are fitted into the groove of cylinder 4, and small diameter part 25 having a radius of curvature that is equal to half a distance between two second axes of rotation A2 and that is smaller than a radius of curvature of the large diameter part 24, 27. Small diameter parts 25 of the pair of gate rods are in contact with each other.
