To provide a slide bearing which can prevent entry of foreign objects and leakage of lubrication grease to maintain slide performance over a long time.SOLUTION: A dust seal 6 closes a gap leading to an annular space 5 formed by an annular protruding part 33 of a lower case 3 being inserted into an annular recessed part 25 of an upper case 2 and is provided with: a first lip part 602 and a second lip part 603 which extend from the annular protruding part 33 side of the lower case 3 and contact with the annular recessed part 25 of the upper case 2. The first lip part 602 is set so that an angle α formed between a direction in which the first lip part 602 extends and a foreign object entry path becomes a narrow angle, and the second lip part 603 is set so that an angle β formed between a direction in which the second lip part 603 extends and a lubrication grease moving path Sout becomes a narrow angle.SELECTED DRAWING: Figure 7

    【課題】異物の侵入および潤滑グリースの漏れを防止して、長期に亘り摺動性能を維持することができる滑り軸受を提供する。【解決手段】アッパーケース2の環状凹部25に、ロワーケース3の環状凸部33が挿入されて形成される環状空間5に繋がる隙間を塞ぐダストシール6に、ロワーケース3の環状凸部33側から延びてアッパーケース2の環状凹部25と当接する第一リップ部602および第二リップ部603を設けている。そして、第一リップ部602の延びる方向と異物侵入経路とのなす角αが狭角となるように第一リップ部602を設定するとともに、第二リップ部603の延びる方向と潤滑グリース移動経路Soutとのなす角βが狭角となるように第二リップ部603を設定している。【選択図】図7
