The present invention relates to a device for manufacturing a hose, whose structure is simple, and which is excellent in durability and watertightness and also secures flexibility because of improved coupling force between a soft part and a hard part, and is able to reduce manufacturing costs because of simple manufacturing processes, and a manufacturing method thereof. The device for manufacturing a hose in accordance with the present invention, comprises: a perforated body (30), wherein a plurality of through holes (31) are formed in a circumferential direction, and a spiral helix is formed in the through hole (31); a plurality of spiral bars (40) coupled to the through holes (31), respectively, by screws; and a rotary body (50) in contact with the spiral bars (40). In this regard, the spiral bars (40) rotate and move frontward by rotation of the rotary body (50). In addition, a soft part (10) is supplied from one side of the spiral bar (40), and a hard part (20) is supplied from the ...
