Description
)に示すように、接続筒1を接続孔6に挿入するときに接続筒1に外嵌したシール材5は径方向(図の矢印方向)に圧縮される。このとき、シール材5は上下に膨らむように変形しようとするが、上面側は接続筒1の段差面4に拘束されるため上側への膨らみは許容されない。このために、内部圧力のバランスが崩れ、シール材5の内径側が図7(b)に示すように下に向かって滑り動く。これによりシール材5に傾きが生じ、その傾きが組み付け完了点でも維持されたままになってシール材の組み付け不良が発生する。なお、接続筒1の外周には潤滑剤が塗布されている場合があり、このときにはシール材5が滑り易くなっているので、上記の問題が特に発生し易い。
径部の外周に至るエアー抜き溝を設けることでその要求に応えている。
