Summary:PURPOSE: To improve manufacturing efficiency while reducing a load for a manufacturing device. CONSTITUTION: A coated high tensile wire in which a preliminary coating inner layer and a preliminary coating outer layer are formed in the outer periphery of a high tensile body is obtained. An SZ spacer is manufactured by forming a spacer main body part in the outer periphery of the coated high tensile wire. In such a case, a mouth piece 10 of a rotating die, which is designed so that a value S1/S2 which is obtained by dividing a cross section area S1 of the formed spacer main body part (a value that the cross section area of the coated high tensile wire 4 is subtracted from the whole cross section area of the spacer) by a resin discharging actual cross section area S2 of the mouth piece used in the case of applying a spacer main body coating (a value that the cross section area of the coated high tensile wire 4 is subtracted from the opening area S of the mouth piece) becomes 1.7, is used. (과제) 제조 장치의 부하를 경감시키면서 제조 효율을 향상시키는 것이다. (해결수단) 항장력체의 외주에 예비 피복 내층, 예비 피복 외층을 형성한 피복 항장력선을 얻는다. 이 피복 항장력선의 외주에 스페이서 본체부를 형성하여 SZ 스페이서를 제조한다. 이 경우, 회전 다이의 구금 (口金; 10) 은 형성되는 스페이서 본체부의 단면적 (스페이서 전체 단면적에서 피복 항장력선 (4) 의 단면적을 뺀 값; S1) 을 스페이서 본체 피복을 실시할 때에 사용하는 구금의 수지 토출 실단면적 (구금 개구 면적 (S) 에서 피복 항장력선 (4) 의 단면적을 뺀 값; S2) 으로 나눈 값 (S1/S2) 이 1.7 로 되도록 설계된 것을 사용한다.
