The invention provides a high-quality seam without causing puckering, by enabling the proper tightening of the threads even in an extra-thin fabric, by keeping a balance between needle and bobbin threads by setting needle thread tension to low tension, by eliminating needle thread slipping-out resistance of the outer periphery of a shuttle. The puckering preventing shuttle device is composed of the inner shuttle 80 for storing a bobbin wound with the bobbin thread, storing a bobbin case removably fixed to a machine frame and stopping rotation by an inner shuttle stopper 90, and an shuttle race cover 70 for internally installing the shuttle 80, having a sword tip 75 and rotated by a lower shaft. The rotational axis O1 of the shuttle race cover 70 is eccentrically arranged to the rotationalaxis of the lower shaft, and a loop of the needle thread scooped up by the sword tip 75.
