Abstract A molded knob of the type which fits over the end of a shaft and is held thereto by means of frictional engagement between the knob and the shaft. The knob has a hub with a shaft receiving socket formed therein. The socket is of irregular transverse cross-section and has a flat wall which engages a flat on the shaft. Fingers formed integrally with the hub extend into the socket. The fingers are located on the opposite side of the socket from the flat wall and are deflected in a direction away from the flat wall upon insertion of the shaft to frictionally secure the knob to the shaft. Stop means are formed in the socket to limit the depth of insertion of the shaft. The fingers extend into the socket beyond the stop means to provide flexibility throughout their contact with the shaft.
A molded knob of the type which frictionally engages and slips over the end of a shaft, a hub formed as part of said knob, a shaft receiving socket formed in said hub, said socket being of irregular transverse cross-section and having a flat wall adapted to engage a flat on said shaft, and elongated fingers formed as part of said hub and extending into said socket on the opposite side of said socket from said flat wall, said fingers extending toward and in alignment with each other and being laterally deflectable in a direction away from said flat wall upon insertion of said shaft into said socket.
