ルト孔（４）を設ける。At both open ends of this octagonal tubular body, two nylon slings (3-1) and (3-2) containing iron cores were placed.
Since both ends of the connection part project, connect this part to the connecting belt (3
-4) is used. A fastening bolt hole (4) is provided at the tip of this belt.
第４図は上記ナイロンスリング製筒形継手を使用して
２台の駆動台車（20）と測定台車（21）を連結してパイ
プライン（22）内に装入した状態を示すものである。FIG. 4 shows a state in which two driving carriages (20) and measuring carriages (21) are connected to each other by using the above nylon sling tubular joint and inserted into the pipeline (22).
すなわち、駆動台車（20）測定台車（21）を連結する
場合は、ナイロンスリング製筒形継手（１）の両端部に
突設した複数個の接続用ベルト（３−４）の先端部を両
台車の前後端部にボルト（23）にて締結する。That is, when connecting the drive carriage (20) and the measurement carriage (21), the tip ends of the plurality of connecting belts (3-4) projecting from both ends of the nylon sling tubular joint (1) are connected. Fasten with bolts (23) to the front and rear ends of the bogie.
したがって、駆動台車（20）と測定台車（21）が互い
に接近しても筒体周壁部に等間隔に装入した４個の鉄芯
（２）がストッパーとなり衝突することがなく、また座
屈することがないため所定の間隔が保持されるのであ
る。Therefore, even if the drive carriage (20) and the measurement carriage (21) approach each other, the four iron cores (2) inserted into the peripheral wall of the cylindrical body at equal intervals serve as stoppers to prevent collision and buckle. Therefore, the predetermined interval is maintained.
また、曲管部通過時においても、鉄芯にて一定の間隔
が保持されるとともに、管内面に接触してもナイロンス
