PROBLEM TO BE SOLVED: To provide a nonwoven fabric production apparatus capable of providing nonwoven fabrics having different widths and saving capital investment without decreasing productivity.SOLUTION: A resin inflow part 21 is provided with a bulging part 41, and a resin supply port part 31 is provided with a recess part 32 for coaxially receiving the bulging part 41. The bulging part 41 has a structure having an outer peripheral surface 41a with a tapered portion having a diameter enlarged toward a tip of the resin inflow part 21. The recess part 32 has an inner peripheral surface 32b with a tapered portion having a diameter decreased toward a tip, and has a structure for receiving the bulging part 41 inside so that the inner peripheral surface 32b abuts the outer peripheral surface 41a of the bulging part 41 to engage the bulging part 41 relatively rotatable in a circumferential direction and inseparably in an axial direction. |
