Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a biaxial different direction rotary extruder that secures the strength of the screw tip without causing restriction for design of a die head, and can reduce the pressure fluctuation in the cylinder by preventing the retention of the resin.SOLUTION: An adapter 5 in which a through-hole 5a that communicates an opening of a cylinder 2 and an opening of a die head 20 is provided is arranged between the cylinder 2 and the die head 20. Protrusion shafts 21 and 22 that project from the cylinder 2 are provided to the ends of the screws 3 and 4. Bearings 23 and 24 that support the protrusion shafts 21 and 22 are provided at the adapter 5.
