A paint roller intended for mounting on a paint frame rod of a paint frame, comprising: - a clamping bush provided with a central opening in which a paint frame rod is clampingly receivable; - a paint roller shaft which has an outer surface with a substantially cylindrical configuration and a first end and a second end located opposite thereto, wherein the outer surface extends around a central axis, wherein the paint roller shaft is provided with a central passage which is collinear with the central axis; - a paint receiving layer which is arranged on an outer surface of the paint roller shaft, wherein the paint receiving layer has a roller outer diameter; - an end part which is nonrotatably connected with the second end of the paint roller shaft; - a stop which is provided with thread and which is included in the end part and which is arranged concentrically with the axis and is adjustable in the direction of the axis through rotation; characterized by: - a handle end plug which by a first handle end plug part is received in the first end of the paint roller shaft and is nonrotatably connected with the paint roller shaft, wherein a second handle end plug part forms a handle which is concentric with said axis and which extends outside the roller shaft, wherein the handle has maximum outer dimensions that lie within an imaginary cylinder whose outer diameter (d) is smaller than the roller outer diameter, wherein in the first handle end plug part there is further provided a clamping bush chamber in which the clamping bush is received rotatably around the axis which is collinear with the substantially cylindrical outer surface, wherein the axial length of the clamping bush chamber is tuned to the length of the clamping bush such that the latter is received in it with slight axial play, wherein the handle end plug is provided with a central passage via which a paint frame rod can be inserted in the central passage of the paint roller shaft for clamped connection of the paint frame rod with the clamping bush and hence for mounting the paint roller shaft on the paint frame rod. - a clamping bush provided with a central opening in which a paint frame rod is clampingly receivable; - a paint roller shaft which has an outer surface with a substantially cylindrical configuration and a first end and a second end located opposite thereto, wherein the outer surface extends around a central axis, wherein the paint roller shaft is provided with a central passage which is collinear with the central axis; - a paint receiving layer which is arranged on an outer surface of the paint roller shaft, wherein the paint receiving layer has a roller outer diameter; - an end part which is nonrotatably connected with the second end of the paint roller shaft; - a stop which is provided with thread and which is included in the end part and which is arranged concentrically with the axis and is adjustable in the direction of the axis through rotation; - a handle end plug which by a first handle end plug part is received in the first end of the paint roller shaft and is nonrotatably connected with the paint roller shaft, wherein a second handle end plug part forms a handle which is concentric with said axis and which extends outside the roller shaft, wherein the handle has maximum outer dimensions that lie within an imaginary cylinder whose outer diameter (d) is smaller than the roller outer diameter, wherein in the first handle end plug part there is further provided a clamping bush chamber in which the clamping bush is received rotatably around the axis which is collinear with the substantially cylindrical outer surface, wherein the axial length of the clamping bush chamber is tuned to the length of the clamping bush such that the latter is received in it with slight axial play, wherein the handle end plug is provided with a central passage via which a paint frame rod can be inserted in the central passage of the paint roller shaft for clamped connection of the paint frame rod with the clamping bush and hence for mounting the paint roller shaft on the paint frame rod.
