Abstract
A locking device includes an annular locking face formed on the inner surface of a casing and an annular lockable face opposed to the locking face and provided on a driven member turnably mounted on the casing. The lockable face is movable into pressing contact with the locking face to lock a lever when the lever is rotated and thereby screwed in toward one direction longitudinally thereof. The locking face and the lockable face are operable free of any local uneven wear, while the lever can be locked to the desired position and unlocked therefrom with high reliability at all times.
