ABSTRACT:
A gauge movement includes a tapered plastic output shaft having a member disposed symetrically thereabout. The member has first and second ends and a conical inner surface disposed about and adapted to receive the tapered plastic output shaft. The conical inner surface extends substantially from the first end to the second end and defines a conical bore through the member. The bore has a first inside diameter at the first end and a second inside diameter, smaller than the first inside diameter, at the second end. The member is further provided with a stepped outer surface having a first outside diameter at the first end and a second outside diameter, larger than the first outside diameter, at the second end. The member further includes at least one slot for deforming the tapered plastic output shaft when the member is forced into engagement with the shaft, to thereby prevent relative rotational movement between the member and the shaft. The slot extends radially from the inner surface to the outer surface and extends axially from the first end toward the second end. A pointer surrounds the member and is secured thereto.
