Abstract
A knob for a gear lever comprises a cap, a gripping section having an axial bore through it and gear teeth about one end of the bore, and an annular anti-rotation member having an axial bore through it and gear teeth about each end of the bore. When assembled, a stem of the cap passes through the axial bores of the gripping section and of the anti-rotation member. The gear teeth of the gripping section mesh with the gear teeth of the anti-rotation member and prevent the member from rotating with respect to the gripping section. A base has an axial bore through it and gear teeth about one end of the bore. The bore has inwardly projecting ribs between which, when the knob is assembled, a spline of the stem of the cap fits at substantially all rotational positions of the spline relative to the base. The gear teeth of the anti-rotation member mesh with the gear teeth of the base and prevent the anti-rotation member from rotating with respect to the base.
