Abstract
A paint roller has a roller support member of a plastic material provided with an internal bearing surface extending for a partial distance from one end for engaging a short shaft portion of a metallic handle which couples the roller to a hand grip. Thrust support in one direction is provided by a transverse surface disposed adjacent one end of the bearing surface for engagement by one end of the shaft and a spring washer which engages the shaft and the roller support provides thrust support in the opposite direction and couples the members together. A short finned section and integrally formed washers on the roller support in the area of the bearing surface are provided for engaging a roller cover adjacent one end. The other end of the roller cover is engaged by a washer supported at one end of an axial extension projecting from the roller support body.
