Dial structure for use with a lock or other mechanism which requires both rotary and axial input movements of an operating spindle. The structure includes an operating knob for imparting both such movements to the spindle, and a dial having position indicia and which is responsive to and follows rotary movement but not lineal movement of the knob. Other features include a bearing connection which provides a universal joint of the spindle in the dial frame, to accommodate minor misalignment of the dial structure with respect to the mechanism. A mask screens all position indicia except that in a narrow aperture, which is visible only to the operator.
