面を有する軸封箱の内部に、一方のシール座面に
端面が当接する第１パツキンと他方のシール座面
に端面が当接する第２パツキンとが同心状に配置
され、第１パツキンはその内周面が上記回転軸に
摺接され、第２パツキンは上記回転軸に摺接する
状態に縮径可能で、かつ縮径方向に弾性的に付勢
されていると共に、上記軸封箱にその外側から抜
出可能に挿入されたカラーにより上記付勢に抗し
て上記回転軸に接触しない状態に拡径されている
ことを特徴とする軸封装置。 Inside the shaft sealing box, which has a pair of seal seats facing each other in the axial direction of the rotating shaft, a first seal whose end surface abuts on one seal seat surface and a second seal whose end surface abuts on the other seal seat surface are installed. The inner circumferential surface of the first packing is in sliding contact with the rotating shaft, and the second packing is capable of contracting in diameter so that it is in sliding contact with the rotating shaft, and is elastic in the direction of diameter reduction. The rotational shaft is biased by a collar inserted into the shaft sealing box so that it can be pulled out from the outside, and the diameter is enlarged so that it does not come into contact with the rotating shaft against the bias. Shaft sealing device.
