Abstract
【解決手段】外周部材1とこの外周部材1に挿入状態で装着した内周部材2との間にシールリング3が介在され、内周部材2の外周面に、この内周部材2の挿入方向へ向けて小径となるテーパ状外周面21及びその小径端部から前記挿入方向へ向けて延びる装着部外周面22が形成され、外周部材1の内周面に、テーパ状外周面21より前記挿入方向側に位置すると共に反挿入方向側を向いた段差面12及びこの段差面12の外径端から反挿入方向へ延びる装着部内周面13が形成され、シールリング3が、テーパ状外周面21及び装着部外周面22と、段差面12及び装着部内周面13の間に圧縮状態で配置される。
【選択図】図1
Description
100%<φB/φA<110%
であることが好ましい。
100%<φB/φA<110%
の関係にあれば、シールリング3は先端外周面23を乗り越える過程でわずかに拡径されるだけなので、シールリング3の残留変形を有効に防止することができる。
