To provide a strut bearing capable of suppressing the entry of mud water and the like into the inside from a clearance on an outer diametrical side than a lower raceway ring between an upper case and a lower case while suppressing an increase in manufacturing costs.SOLUTION: A strut bearing 1 is equipped with an upper case 2, a lower case 3, an upper raceway ring 4, a lower raceway ring 5, and a rolling body 6. The upper case 2 and the lower case 3 are made of synthetic resin. On an opposite surface 3A of an axial clearance B between the upper case 2 and the lower case 3 which is located on an outer diameter side than the lower raceway ring 5, one or more of protrusion rows E are provided, in which protrusions 9 protruding from the lower case 3 toward the upper case 2 are arranged at intervals in a circumferential direction.SELECTED DRAWING: Figure 3

    【課題】製造コストの上昇を抑えながら、上側ケースと下側ケースとの間の、下側軌道輪よりも外径側の隙間から泥水等が内部へ浸入することを抑制できるストラットベアリングを提供する。【解決手段】ストラットベアリング1は、上側ケース2、下側ケース3、上側軌道輪4、下側軌道輪5、転動体6を備える。上側ケース2及び下側ケース3は、合成樹脂製である。下側軌道輪5よりも外径側に位置する、上側ケース2及び下側ケース3間の軸方向隙間Bの対向面3Aに、下側ケース3から上側ケース2へ向かって突出する突片9を周方向に間隔を空けて並べてなる突片列Eを一列以上設ける。【選択図】図3
