Abstract

　使用中に軸棒が緩むことを防止できると共に、ガスを流通する場合にガス漏れをも防止することができるストッパー構造体を提供する。ストッパー耐火物２の装着孔２ａに装着される軸棒１の先端部分の周方向外面に、ストッパー軸方向下端側に向けて拡径する第１のテーパー面４ａを形成すると共に、ストッパー耐火物２の装着孔２ａの内面に、第１のテーパー面４ａと面合する第２のテーパー面４ｂを形成し、第１のテーパー面４ａと第２のテーパー面４ｂが面合して密着するように軸棒１をストッパー耐火物に対して締め付ける。そして、軸棒１の先端部分の形状が、軸棒１のストッパー耐火物上端面２Ｓ位置から第１のテーパー面４ａの起点位置までの長さをＡ、第１のテーパー面４ａの起点位置の外径をＤ、第１のテーパー面４ａのテーパー角度をθとする場合に、ｔａｎθ≦Ｄ／２Ａの関係を満たすようにする。
