Abstract

【課題】シールの密封性能の向上を図り、軸受性能を長期間に亘って維持することができる車輪用軸受装置を提供する。 【解決手段】外方部材３のアウター側の端部にバックアップシール１６が装着され、このバックアップシール１６が、外方部材３の端部外周に圧入される円筒状の芯金１４と、この芯金１４に一体に加硫接着されたシール部材１７とからなると共に、シール部材１７が、径方向外方に傾斜して延び、先端部が拡径するラッパ状に形成されて車輪取付フランジ６のインナー側の側面６ｃに摺接されたサイドリップ１５ｂを有し、このサイドリップ１５ｂの基部１７ａが芯金１４のインナー側の端部を覆うように固着されているので、車輪取付フランジ６と外方部材３が近接した構造であっても、シール部材１７のスペースを充分に確保することができ、サイドリップ１５ｂの適切な接触圧を有する最適設計ができる。
