Abstract

　耐泥水性能を向上させることができ、かつ断面高さを低くすることができる軸受密封装置、およびそれを用いた車輪用軸受を提供する。この軸受密封装置１は、車輪用軸受の相対回転する内方部材と外方部材間に設けられるものであり、環状のシール板２と弾性シール部材３とでなる。シール板２は、内方部材の外周に嵌合する円筒部２ａと、その端部から立ち上がる立板部２ｂとでなる断面Ｌ字状である。弾性シール部材３は、芯金４に弾性体５を固着してなる。芯金４は、外方部材の内周に嵌合する円筒部４ａと、その端部から立ち下がる立板部４ｂを有し、シール板２と対向する断面逆Ｌ字状である。弾性体５は、芯金４の径方向に並び、先端がシール板２の立板部２ｂに接する２枚のサイドリップ５ａ，５ｂを有し、サイドリップ５ａ，５ｂ間の距離は０．１mm以上である。
