Abstract

PURPOSE: To eliminate the need of an opener mechanism, to simplify a structure and to dissolve noise by collisions by making rotary force to an inner shuttle by a bobbin thread act in the opposite direction of the rotary force by the friction of an outer shuttle. CONSTITUTION: A bobbin thread take-out port 7 is formed in a slit shape within the range of 2 right angles by the clockwise rotation of the outer shuttle 1 with a line segment for connecting the center of a bobbin support fitted to a bobbin support hole 6 at the time of mounting a bobbin case 1 to the inner shuttle 2 and an inner shuttle stopper 22 disposed on the inner shuttle 2 as a reference. Also, on the outer shuttle 3, the need of the horizontally rotating shuttle device of an opener or the like is eliminated. When a sewing machine is rotationally driven, the outer shuttle 3 is rotated in the direction of an arrow A. For that, since the bobbin thread 61 from a bobbin taken out through the bobbin thread take-out port 7 is delivered in the direction of rotating the inner shuttle 2 in the opposite direction of the arrow A by the tension, for the pressurizing force to a stopper 24a of a throat plate 23 acting on the inner shuttle stopper 22, the frictional force to the inner shuttle 2 of the outer shuttle 3 and the tension accompanying the delivery of the bobbin thread 61 are offset and practically become almost zero and a needle thread 60 is easily put around the outer periphery of the inner shuttle 2 without the operation of the opener mechanism.
