Abstract

【課題】検出部の密封性を高めて異物が侵入するのを防止すると共に、検出精度を高めて長期間に亘って信頼性を維持させた回転速度検出装置付き車輪用軸受装置を提供する。 【解決手段】センサホルダ１０を構成するカバー２６が、耐食性を有する非磁性体の鋼板からなり、外方部材５の端部に外嵌される円筒状の嵌合部１１ａと、これから径方向内方に延びる鍔部１１ｂと、さらに径方向内方に延びる底部１１ｃとからなると共に、この底部１１ｃの内縁から内輪２方向に延長させて湾曲部２６ａが形成され、この湾曲部２６ａの内径が内輪２の外径よりも小径に形成されて内輪２との間に所定の軸方向すきまを有するラビリンスシール２７が構成され、この軸方向すきまが０．５～２．０ｍｍの範囲に設定されているので、エンコーダ１６に外部から小石等が直接衝突して破損するのを防止し、検出部の密封性を高めることができる。
