A rolling device for a device to enable the moving of the device along a surface comprises a wheel axle carrying a wheel, a lead screw with a nut, at least one axle support member rotatably connected in one end in a fixed pivot point and in the other end connected to the lead screw nut, and a drive motor connected to the lead screw to rotate the lead screw for displacing the lead screw nut and thereby displacing the wheel between an extended position and a retracted position. Each axle support member supports an end portion of the wheel axle, and the wheel has two side faces. The lead screw is arranged tangentially to the rotational direction of the wheel between the two side faces of the wheel at a distance from the wheel axle larger than the radius of the wheel.
