摘要：【課題】簡単な加工によって軸受の内部に異物が侵入するのを防止することができる軸受の異物侵入防止構造を提供する。【解決手段】異物侵入防止構造11は、軸受3に異物Sが侵入するのを防止する。異物侵入防止構造11は、軸受3側の接触面3gと後蓋8側の接触面8aとの間に発生する摩耗粉(フレッチング摩耗粉)のような異物Sが軸受3内に侵入するのを防止する。収集部12は、軸受と後蓋8との間の接触面3g,11の摩耗によって発生する異物Sを収集する。収集部12は、後蓋8側の接触面8aの接触面圧が最も高くなる領域で異物Sを収集する。収集部12は、後蓋8側の接触面8aの接触面圧が最も高くなる領域に形成されることによって、この接触面圧を緩和し接触面3g,11における異物Sの発生を抑制する。【選択図】図4
