Abstract
The present invention provides a sewing machine shuttle that allows, prior to the application of an upward-pulling force from a take-up lever and without the use of this upper-pulling force, an upper thread to be pulled from an internal shuttle while sliding through the abutment between a rotation stopping recess portion and a rotation stopping projection; prevents thread breakage and inconsistency in thread tension by avoiding resistance from the upper thread when the upward-pulling force of the take-up lever is applied; and stabilizes the action of the upper thread after it has been pulled from the inner shuttle.
