发明名称 Wellrohr aus schraubenförmig gewickeltem Band
摘要 The present invention provides a tubular member construction (1) capable of preventing the end portion (7) of a flexible pipe (1) formed of a band member (3) from coming loose without costing. The flexible pipe (1) is formed by winding a metallic tubular member (3) in a spiral shape in an overlapped manner, and a plurality of wavy corrugations (4,5) are formed on the peripheral wall surface of the flexible pipe (1) continuously in the axial direction. In order to prevent a band member (3) located in an end portion (7) of the flexible pipe (1) from coming loose, collapsed portions are formed on corrugations (4,5) located in the end portions (7) of the tubular member (1). <IMAGE>
