A quick feeding shaft is rotatably supported at a bed of a perforating sewing machine. A quick feeding shaft rotatable in one direction and has one end coaxially connected to a magnetic clutch shaft and the other end coaxially connected to one end of a quick feeding shaft body provided with a worm. A magnetic clutch is secured coaxially to the magnetic clutch shaft and operatively connects the magnetic clutch shaft to the quick feeding shaft. A pattern wheel shaft is disposed at right angles to the quick feeding shaft and has a pattern wheel for feeding a sewn cloth quickly. A worm wheel coaxially secured thereto at an intermediate portion thereof to mesh with the worm. The worm wheel and the worm form a gear mechanism for transmitting the rotational driving force of the quick feeding shaft to the pattern wheel shaft.
