Abstract
A shaft retaining device having a shaft selectively retained as to translation and rotational movement. A sleeve coaxial with the shaft encloses a length of the shaft. The shaft has an outwardly projecting cam within the sleeve. A cam follower carried by the sleeve has a part thereof within the sleeve in a plane normal to the shaft axis and is cammed away from the shaft by the cam. The cam and cam follower have complementary profiles, one of which is a male profile and the other is a female profile, in which the cam and cam follower engage other effectively selectively immobilizing the shaft and sleeve as to relative translation movement when the cam and cam follower engage each other.
