Method of producing drag on an operating rod

摘要

A holder for supporting a rod for rotation or longitudinal movement is molded from a plastic material. The holder is T-shaped having a central elongated portion through which the rod extends and transverse wings with apertures therethrough by which the holder is supported on a member. The cavity in the mold has a rod extending therethrough with a ring of elastomeric material thereon about which the plastic material is injected to mold the holder as a unit element with the elastomeric ring retained therein when the supporting rod is pulled therefrom. It is only necessary to insert the operating rod within the holder through the elastomeric ring which will be compressed so that it will apply a predetermined drag on the rod to restrict its longitudinal and rotational movement.
