A plurality of stretched monofilaments (2) are spirally wound at an equal pitch in a hose axial direction while the stretched monofilaments (2) are arranged, whereby a pressure-resistant performance in the portions does not deteriorate even when a pitch (S) between these stretched monofilaments (2, 2) narrows and a diameter of the monofilaments is reduced. Therefore, the stretched monofilaments having a small diameter is usable. |
