Abstract
A gauge includes a transparent pointer driven through gears by a stepper motor offset from the pointer axis. An output gear on the pointer axis is transparent and has a first hub supporting the pointer and a second hub aligned with a lamp, so that light is passed through the output gear to the pointer. The first hub has retention pads molded onto its side. The pointer has a tubular sleeve with axial slots to allow expansion and has retention ribs which ride over the pads upon assembly and snap over the pads to secure the pointer in an axially fixed position. The sleeve also has tapered axial ribs which slide between the pads during assembly to angularly orient the pointer.
