Abstract
【解決手段】内輪1と外輪2の間の軸受空間を内側と外側の2つの接触シール5、6で密封し、これらの内側と外側の各接触シール5、6にそれぞれ内外2枚のシールリップ5c、5d、6c、6dを設け、内側の接触シール5の各シールリップ5c、5dをシール摺接面1aに線接触させ、外側の接触シール6の各シールリップ6c、6dをシール摺接面2aに面接触させることにより、外側の接触シール6の各シールリップ6c、6dで泥水を完全に遮断するとともに、これらのシールリップ6c、6dの面接触界面から浸入する水分を、内側の接触シール5の線接触する各シールリップ5c、5dで水切りして遮断し、泥水が飛散する環境で使用しても、シール性を十分に確保できるようにした。
