Abstract
An integral door knob assembly for mounting on a face of a door has a spring return so that the door knob rotates to one position when released. A shank formed integral with or attached to the door knob is formed of plastic material eliminating the requirement of a separate plastic bushing in the rose member, and has flexible fingers to provide a snap lock between a spring assembly member and the end of the shank to hold the knob assembly to the rose member. The spring assembly member is also formed of plastic material and has sufficient flexibility to allow a torsion spring to be inserted and removed.
