(1)第1筒体6の拡径部22が第2筒体7の一方側部分40を囲んでいることで、第2筒体7の熱膨張が、スリーブ3の内側(配管13又は配線に接近する側)に向かうものとなる。
(2)非膨張性材10が、第1筒体6の本体部20の内部や、位置調整筒体8の内部に配置されることで、スリーブ3の軸方向(配管13又は配線側)に向かう第2筒体7の膨張が規制され、スリーブ3の内側(配管13又は配線側)に向かう第2筒体7の膨張が促進される。
(3)スリーブ3の中空部Eにおける、第2筒体7の内部以外の範囲に、非膨張性材10や固定枠9が配置されることで、非膨張性材10や固定枠9が、第2筒体7の熱膨張の妨げにならない。
(1)第1筒体6の拡径部22が第2筒体7の一方側部分62(上側部分)を囲み、第3筒体52の拡径部55が第2筒体7の他方側部分63(下側部分)を囲んでいることで、第2筒体7の熱膨張が、スリーブ51の内側(配管13又は配線に接近する側)に向かうものとなる。
(2)非膨張性材10が、第1筒体6の本体部20の内部や、第3筒体52の本体部53の内部や、位置調整筒体8の内部に配置されることで、火災の発生時には、スリーブ51の軸方向(配管13又は配線側)に向かう第2筒体7の膨張が規制され、スリーブ51の内側(配管13又は配線側)に向かう第2筒体7の膨張が促進される。
(3)スリーブ51の中空部Eにおける、第2筒体7の内部以外の範囲に、非膨張性材10や固定枠9が配置されることで、非膨張性材10や固定枠9が、第2筒体7の熱膨張の妨げにならない。
