摘要：A drive roller unit for driving an article on a conveyor track includes a driveroller which can be driven in rotation by an electric motor. The drive roller is in the formof a hollow circular cylinder and the motor is accommodated in the interior thereof. Thedrive roller is non-rotatably connected to the stator of the motor in concentric
relationship with the axis of rotation of the rotor of the motor. A runner wheel disposedat least at one axial end of the rotor shaft is in engagement with a guide track mechanismwhich is fixedly connected to the base of the unit and which leads upwardly with respectto the base, the runner wheel rolling along the guide track mechanism to raise the driveroller into an upper operative position to engage an article to be driven thereby. Theguide track mechanism may be in the form of a guide wheel co- operable with the runnerwheel.
