Abstract
A headgear frame apparatus comprises: a headgear frame for clamping a headgear; and a rotary drive frame for fitting the headgear frame replaceably thereon on the side of a sewing machine. The headgear frame is provided at its outer circumference with a brim which is further projected outward. On the outer circumference of the rotary drive frame, there are tiltably hinged levers which have hook pawls projected toward the rotary drive frame and which are biased by springs in the direction where the hook pawls approach the rotary drive frame. When the headgear frame is fitted on the rotary drive frame, the brim once raises the hook pawls in the direction away from the rotary drive frame, and after the hook pawls rode over the brim, the hook pawls are hooked on the brim by the biasing forces of the springs.
