ABSTRACT:
A magnetic shaft guard for use with a rotating shaft has a permanent magnet to hold the guard in place on the rotating shaft. Sufficient clearance is present between the shaft and an inner diameter of the guard so that the guard will cease rotation freely relative to the shaft should external contact with the guard occur. The magnet is loosely mounted within a cavity near the tip of the shaft guard so that the magnet is able to cant and thereby adhere better to shafts with tips which are not squarely cut. A spiral or other design may be placed on the guard to visually alert persons in the vicinity that the shaft is rotating.
