A paint roller frame and cage assembly mounted for rotation on a shaft portion of the roller frame. The cage assembly includes a plurality of circumferentially spaced, axially extending support bars joined together by a plurality of ribs providing an annular support for uniformly supporting a roller cover thereon. At the inboard end of the support bars is an annular flange having an outer diameter less than the outer diameter of the annular support. Mounted on the annular flange is a retaining spring including a Belleville type spring washer having circumferentially spaced apart spring fingers extending radially and axially outwardly from the outer periphery of the washer for frictionally retaining the roller cover on the cage assembly. The Belleville type spring washer is retained on the annular flange by an end cap having a first annular sleeve telescopingly received over the annular flange. A radial shoulder on the end cap acts as a stop for locating the roller cover on the cage assembly when the roller cover is fully inserted thereon. The end cap also includes a second annular sleeve radially outwardly spaced from the first sleeve having an outer diameter substantially corresponding to the outer diameter of the annular support to provide a continuation of the annular support for supporting the roller cover up against the radial shoulder on the end cap, but with a clearance space between the end of the second annular sleeve and adjacent ends of the support bars for receipt of the retaining spring fingers therein.
