ABSTRACT:
An operating crank for a window regulator mechanism includes a one piece molded handle having a visible side and a non-visible side when mounted at one end to a driven mechanism. A knob is rotatably attched to the visible side of the other end of the handle by an attachment located generally in the area where the knob is gripped by an operator. The attachment includes a series of molded ribs on a shank which extends axially from the visible side of the handle and which rotate within a groove inside the knob. The knob retention ribs extend radially of the shank and are molded integrally to the shank by means of a die insert receivable through access slots defined through the knob end of the handle from the non-visible side of the handle, giving access to the coplanar bottom surfaces of the knob retention ribs. The retention ribs may thereby be molded without leaving a visible parting line on the visible side of the handle.
