摘要

Disclosed is an apparatus for holding knobs for turning a channel selector of a television receiver or for similar purposes. A flat plate having a first group of projections adapted to bear against a notched flat portion of a rotatable shaft (tuner shaft) having a semi-circular section, and a second group of projections arrayed to bear against a portion of knob into which the shaft is inserted is employed to obtain a reliable coupling of the shaft and the knob.
