Zusammenfassung:	To knead the molten resin more uniformly.SOLUTION: The kneading adjustment mechanism 80 has a pair of movable members 81, 82, each of which has a channel forming surface 85 forming part of a flow path 20 through which the kneaded molten resin is conveyed, and a screw 84 disposed between the channel forming surfaces 85 of the respective movable members 81, 82. At least one of the pair of movable members 81, 82 is operable to increase or decrease the gap between the flow path forming surface 85 and the screw 84, and at least one protrusion 86 is provided on the periphery of the screw 84.SELECTED DRAWING: Figure 3 【課題】溶融樹脂をより均一に混練する。【解決手段】混練調整機構８０は、混練された溶融樹脂が搬送される流路２０の一部を形成する流路形成面８５を備える一対の可動部材８１，８２と、それぞれの可動部材８１，８２の流路形成面８５の間に配置されるスクリュー８４と、を有する。一対の可動部材８１，８２の少なくとも一方は、流路形成面８５とスクリュー８４との間の隙間が増減するように動作可能であり、スクリュー８４の外周には、少なくとも１つの突起部８６が設けられる。【選択図】図３
