PROBLEM TO BE SOLVED: To provide a clutch structure for a presser foot of an embroidery sewing machine, which prevents unnecessary driving of a presser foot to reduce vibration and noise. SOLUTION: This clutch structure for a presser foot in an embroidery sewing machine includes: a guide member, to which the presser foot drive link is rotatably connected, and through which the needle bar guide shaft passes, a spring connecting member mounted on the outer circumference of the needle bar guide shaft and inside the guide member, a resilient member mounted on the outer periphery of the spring connecting member, and a pivot member mounted inside the guide member so as to be pivotable around the needle bar guide shaft within a right and left predetermined angular range by a height adjusting means for a presser foot and the resilient member.
