Abstract
Apparatus to axially hold a featureless shaft has an abutment for abutting the side of the shaft and a cam to wedge the shaft against the abutment. The cam has a convexly radiused face which is generally opposed to the abutment. The generating radius for the face is offset from the pivot axis of the cam in the direction in which a shaft is inserted into the apparatus. Consequently, once the cam wedges the shaft against the abutment any withdrawal force on the shaft will tighten the wedging effect since the eccentric radiused face will attempt to move closer to the abutment.
