    • An internally threaded body is described. A clockwise spiral thread and a counter-clockwise spiral thread are provided as a pair. The internally-threaded body (1180) has a clockwise or counter-clockwise intermittent or continuous spiral thread (1183) formed on the inner circumferential surface of a tubular member having a roughly tubular shape, and has, on one end in the tubular direction of the tubular member, reverse rotation preventing means for preventing reverse rotation relative to the direction of rotation when screwed onto the duplex threaded body. The reverse rotation preventing means has one or more plate pieces (1186,1187), the plate piece is arranged protruding from the inner circumferential surface of the tubular member towards the axis of rotation of the internally-threaded body, the end portion of the plate piece serves as a clockwise or counter-clockwise spiral thread, and the thread formed by the end of the plate piece has a finite inclination angle relative to a lead angle of the thread formed on the inner circumferential surface of the tubular member.
    • 描述内螺纹体。 一对顺时针螺旋线和逆时针螺旋线。 内螺纹体(1180)具有形成在管状构件的内周面上的顺时针或逆时针间歇或连续的螺旋形螺纹(1183),其具有大致管状形状,并且在管状方向的一端 管状构件,用于当拧在双面螺​​纹体上时防止相对于旋转方向的反向旋转的反向旋转防止装置。 反转防止装置具有一个或多个板件(1186,1187),板件从管状件的内周表面朝向内螺纹体的旋转轴线突出,板件的端部 片作为顺时针或逆时针螺旋形螺纹,并且由板件的端部形成的螺纹相对于形成在管状构件的内周表面上的螺纹的导程角具有有限的倾斜角。
