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。車体取付用のフランジ１ａを有し、このフランジ１ａは、各ボルト孔１４が設けられた円周方向部分が他の部分よりも外径側へ突出した突片１ａａとされる。前記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と１つ以上の切欠き部２０ｂを有する歪み発生部材２０、およびこの歪み発生部材２０の前記切欠き部２０ｂの周辺の歪みを検出するセンサ２１を有するセンサユニット１９を、前記固定側部材の外径面に対して２つ以上の接触固定部２０ａが軸方向に同寸法の位置に来るように設ける。前記２つ以上の接触固定部２０ａは、固定側部材の軸心回りに互いに開く角度を持ち、前記センサユニット１９の両端に設けられた接触固定部２０ａ間の角度が、前記固定側部材の隣り合う前記突片１ａａの間の角度の半分以下となるように設置する。
