Abstract

　ヒステリシスの影響を受けることなく車輪に係る荷重を精度良く検出できるセンサ付車輪用軸受を提供する。この車輪用軸受は、複列の転走面３が内周に形成された外方部材１と、上記転走面３と対向する転走面４を外周に形成した内方部材２と、両部材の対向する転走面３，４間に介在した複列の転動体５とを備える。上記外方部材１および内方部材２のうちの固定側部材の外径面に、少なくとも１つのセンサユニット１９が設けられる。センサユニット１９は、固定側部材の外径面に接触して固定される２つ以上の接触固定部２０ａを有する歪み発生部材２０、およびこの歪み発生部材２０に取付けられてこの歪み発生部材２０の歪みを検出するセンサ２１を有する。前記固定側部材の外径面における前記センサユニット１９の隣合う２つの被接触固定部１ｂの間には溝２５が設けられる。
