本発明のエンコーダ付組み合わせシールリングとこれを組み込んだ車輪支持用転がり軸受ユニットとのうち、請求項１に記載したエンコーダ付組み合わせシールリングは、静止輪の周面と回転輪の周面との間に存在する空間部の開口端部を塞ぐと共に、上記回転輪の回転速度を検出する為に使用する。
そして、上記静止輪の周面に固定されるシールリングと、上記回転輪の周面に固定される金属製のスリンガと、このスリンガに支持固定されるエンコーダとを備える。
又、上記シールリングは、上記静止輪の周面に嵌合固定される固定円筒部及びこの固定円筒部の端縁から上記回転輪の周面に向け折れ曲がった固定円輪部から成る芯金と、この芯金の全周に亙って添着された、シールリップを有する弾性材とを備える。
又、上記スリンガは、磁性ステンレス鋼板製で、上記回転輪の周面に嵌合固定される回転円筒部と、この回転円筒部の端縁から上記静止輪の周面に向け折れ曲がった回転円輪部とを備えて、シールリップを有する弾性材は備えず、上記回転円筒部の周面及び上記回転円輪部の片側面で上記シールリップの先端縁を摺接させる部分を平滑面とすると共に、上記回転円輪部の他側面で上記エンコーダを支持固定すべき面を上記周面及び片側面よりも表面粗さの値が大きい粗面としている。尚、本明細書で言う粗面とは、上記シールリップの先端縁を摺接させる平滑面に比較して粗い面を言い、必ずしも一般的に言われる粗面程粗くない場合も含む。
更に、上記エンコーダは、円周方向に亙ってＳ極とＮ極とを交互に配置したゴム磁石製で、上記回転円輪部の他側面に結合固定されている。
又、上記固定円筒部は、上記固定円輪部から遠い側の先端部の外径が中間部の外径よりも小さくなっており、この先端部の外周面が上記弾性材の一部により被覆されている。

Further, the seal ring includes a fixed cylindrical portion fitted and fixed to the peripheral surface of the stationary wheel, and a cored bar including a fixed circular portion bent from an end edge of the fixed cylindrical portion toward the peripheral surface of the rotating wheel. And an elastic material having a seal lip attached around the entire circumference of the core.
The slinger is made of a magnetic stainless steel plate , and has a rotating cylindrical portion fitted and fixed to the peripheral surface of the rotating wheel, and a rotating ring bent toward the peripheral surface of the stationary wheel from the end edge of the rotating cylindrical portion. And no elastic member having a seal lip, and a portion which makes the tip edge of the seal lip come in sliding contact with the circumferential surface of the rotary cylindrical portion and one side surface of the rotary annular portion is a smooth surface The surface on which the encoder should be supported and fixed on the other side surface of the rotating circular ring portion is a rough surface having a surface roughness value larger than that of the circumferential surface and one side surface. The term "rough surface" as used herein refers to a rough surface as compared to a smooth surface which is brought into sliding contact with the tip edge of the seal lip, and also includes the case where the surface is not as rough as generally said.
Furthermore, the encoder is made of a rubber magnet in which the S pole and the N pole are alternately arranged in the circumferential direction, and is coupled and fixed to the other side surface of the rotating circular ring portion.
