Zusammenfassung:	A rotary control knob apparatus (10) includes a stationary knob retainer (16) having a cylindrical post (22) and an annular knob (14) that slides over the retainer post (22), where the exterior periphery of the retainer post (22) has a distributed array of compliant protrusions (46) that contact the inner periphery of the knob (14) to provide a resilient sliding interference fit between the knob (14) and the retainer post (22). In a preferred arrangement, the retainer (16) is secured against the rear surface of a control panel trimplate (12), and the knob (14) is axially captured between the trimplate (16) and a retainer flange (24) extending radially outward from the base of the cylindrical post (22).
