Description
図3(a)に示すように、保護カバー9は、円筒状の大径部9aと小径部9cとが所定の角度θからなるテーパ部9bで連結されている側部と中央部が突出した円盤状の底部9dとから形成されている。保護カバー9は、大径部9aの一端と小径部9cとの他端とがテーパ部9bを介して接続され、小径部9cの他端に底部9dの外縁が一体に連結されている。つまり、保護カバー9は、一側端に底部9dが形成され、他側端が開口している。保護カバー9は、テーパ部9bと小径部9cとにNBR(アクリロニトリル−ブタジエンゴム)、耐熱性に優れたHNBR(水素化アクリロニトリル・ブタジエンゴム)、EPDM(エチレンプロピレンゴム)、耐熱性、耐薬品性に優れたACM(ポリアクリルゴム)、FKM(フッ素ゴム)、あるいはシリコンゴム等の合成ゴムからなる環状のシール部材10が加硫接着によって一体的に設けられている。シール部材10には、環状突出部である環状のシールリップ10aと突出面10bとが一体に形成されている。
図6(b)に示すように、センサホルダ11は、側部11aの鍔部11bが外輪2の一側端に接触するまで外嵌合孔13の内側に向かって移動される。
