Claims (2)
- 一方の管の端部に形成された受口の内部に他方の管の端部に形成された挿口が挿入されるとともに、受口と挿口との間で管軸方向の推進力が伝達される管継手であって、受口の外側における挿口の部分に第1の環状体と第2の環状体とが外ばめされ、第1の環状体は受口の端面に接触しており、第2の環状体は挿口の外周に形成された環状溝にはまり込んでおり、前記第1の環状体と第2の環状体とは、受口から遠ざかるにつれて次第に拡径するテーパ面によって互いに接触しており、第1の環状体は、この第1の環状体を径方向に貫通して挿口の外面に接する周方向に複数の芯出しボルトによって、挿口に対して芯出しされていることを特徴とする管継手。
- 第1の環状体における第2の環状体よりも受口から遠い位置に、推進力の伝達中に環状溝から浮き上がるように力を受けた第2の環状体を、前記力が解消したときに環状溝へ戻るように案内する案内部材を設けたことを特徴とする請求項1記載の管継手。
