Abstract

　センサユニットにおける歪み発生部材の切欠き部隅部に歪みが集中するのを回避して、車輪にかかる荷重を正確に検出できるセンサ付車輪用軸受を提供する。車輪用軸受は、外方部材と内方部材の対向し合う複列の転走面間に転動体を介在させたものである。外方部材と内方部材のうち固定側部材に１つ以上のセンサユニット２０を設ける。センサユニット２０は、固定側部材に接触して固定される２つ以上の接触固定部を有する歪み発生部材２１と、この歪み発生部材２１に取付けられてこの歪み発生部材の歪みを検出するセンサ２２とからなる。歪み発生部材２１は前記接触固定部間に切欠き部２１ｂを有し、その切欠き部２１ｂの隅部を断面円弧状としている。
