Abstract
軽量化を図った軽合金製ナックルに装着され、温度上昇による予圧低下と軸受クリープを防止した車輪用軸受装置を提供する。
【解決手段】
軽合金からなるナックルに嵌合された車輪用軸受3を備えた車輪用軸受装置において、外輪12の外周に環状溝18が形成され、この環状溝18に、ポリアミド系の合成樹脂で、線膨張係数が8〜16×10−5/℃に設定された樹脂バンド19が射出成形によって充填されると共に、環状溝18の側壁18aが開口方向に広がるように傾斜し、環状溝18の断面が略台形形状に形成されているので、成形直後の冷却により樹脂バンド19が斜めに収縮し、樹脂バンド19と側壁18aとの間に発生する軸方向の空隙20を最小限に抑制することができ、温度上昇時、樹脂バンド19が効果的に径方向に膨張して嵌合シメシロの低下を抑制し、軸受クリープの発生を防止することができる。
