To provide a slide bearing which has excellent assembly workability, can achieve downsizing, and is excellent in slide performance despite having a dust seal.SOLUTION: A slide bearing includes: an upper case 2 having an annular recessed part 25 on its lower surface 24; a lower case 3 having an annular protruding part 33, which is inserted into the annular recessed part 25 of the upper case 2 to form an annular space 5, on its upper surface 32; a center plate 4 which is disposed in the annular space 5 and achieves relative rotation between the upper case 2 and the lower case 3; and a dust seal 6 which closes a gap leading to the annular space 5. An outer seal part 60 of the dust seal 6 has a lip part 603 which extends from the annular protruding part 33 of the lower case 3 to the upper side in an axis O direction and contacts with a bottom surface 26 of the annular recessed part 25 of the upper case 2.SELECTED DRAWING: Figure 2
【課題】ダストシールを有しつつも、組み立て作業性に優れ、小型化を図ることができ、かつ摺動性能に優れた滑り軸受を提供する。【解決手段】下面24に環状凹部25を有するアッパーケース2と、上面32にアッパーケース2の環状凹部5に挿入されて環状空間5を形成する環状凸部33を有するロワーケース3と、環状空間5に配置されてアッパーケース2およびロワーケース3間の相対的な回動を実現するセンタープレート4と、環状空間5に繋がる隙間を塞ぐダストシール6と、を備える。ダストシール6の外側シール部60は、ロワーケース3の環状凸部33から軸O方向上方に延びてアッパーケース2の環状凹部25の底面26と当接するリップ部603を有している。【選択図】図2
