The designed structure relates to the clutch drive of the sewing machine feed water, the clutch structure inside the clutch disc and the outer clutch disks are rotated intermittently in a predetermined direction from each other, this rotation driving of the sewing needle to feed and water feed shaft, and ensure that the water feed sewing action occurs, the inner clutch and the outer clutch discs each disc of the annular By the action of the friction surfaces and friction discs combined with each other, the friction surface of the friction disk drive can withstand the pressure of the full annular surface is a concern that no scratch. Friction disc is supported by a compression spring with adjustable pressure, whereby within, relatively accurate electromotive force is generated between the outer friction disc clutch, the outer clutch disc clutch generates a thrust in the axial direction using a connecting rod mechanism, friction intermittent contact between the disc and the rotation takes place in.
