ABSTRACT:
A safety structure, for use in a work rotating apparatus for a laser beam machine having a manually rotatable shaft and work holder supported by a frame, comprises a pin and a pair of stops. The stops are separately located along a circular arc which is coaxial with the shaft. The stops contact the pin to limit the angle of rotation of the shaft which prevents the rotatable work holder, and the workpiece held by said work holder, from colliding with the frame.
