Abstract

　ヒステリシスの影響を受けることなく車輪にかか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、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。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つの接触固定部２０ａ，２０ｂを有する歪み発生部材２０、およびこの歪み発生部材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２１を有する。このセンサユニット１９の２つの接触固定部２０ａ，２０ｂは、互いに固定側部材の円周方向における同位相の位置に配置される。
