STRUT BEARING AND VEHICLE STRUT SUSPENSION

An upper raceway ring has an inward flange portion. A lower raceway ring has an outward flange portion. An upper case has an outwardly projecting piece projecting in the radially outward direction toward an end surface of the inward flange portion from a surface facing the end surface. A lower case has an inwardly projecting piece projecting in the radially inward direction toward an end surface of the outward flange portion from a surface facing the end surface. The end surface of the upper raceway ring comes into contact with the outwardly projecting piece of the upper case, to allow the upper raceway ring to be held by the upper case. The end surface of the lower raceway ring comes into contact with the inwardly projecting piece of the lower case, to allow the lower raceway ring to be held by the lower case.
