Abstract

スリンガーおよびリップシールの組み合わせよりなる磁気エンコーダー付きの密封装置において、複数の製品を積み重ねたときに吸着防止突起が内周側に倒れることがなく、もって製品積み重ね時の安定性を確保することができる密封装置を提供する。この目的達成のため、相対回転する二部材のうちの一方に装着されるスリンガーと、他方に装着されるリップシールとの組み合わせよりなり、スリンガーはその軸方向一方の端面に磁気エンコーダーを有し、リップシールはスリンガーに摺動自在に密接するシールリップを取付環に被着したものであって、取付環の軸方向他方の端面にはゴム状弾性体よりなる製品積み重ね時の吸着防止突起を設けてなる密封装置において、吸着防止突起７は、その断面形状を先細り状とされ、かつその内周側側面７ａは外周側側面７ｂよりも大きな角度で回転軸線０に対して傾斜する形状とされていることを特徴とする。
