SHUTTLE BODY OF SEWING MACHINE

摘要

PROBLEM TO BE SOLVED: To enable the easy mounting to a shuttle and exchange of a bobbin- thread bobbin or a bobbin-thread bobbin integrated shuttle bobbin case by arranging a shuttle at the tip part of a shuttle body distant from a hook shaft and forming an opening part for mounting the bobbin-thread integrated shuttle bobbin case to a shuttle body at the part of the shuttle body close to the hook shaft. SOLUTION: In a sewing machine, a shuttle K (K') in which the location of the tip of a rotating hook is set correspondingly to the location of a sewing needle 1 (1') to be raised and lowered with the rotation of an upper shaft is disposed in a sewing machine bed. In the shuttle body K, a shuttle mount B with an opening part Ba is mounted to the end part of a hook shaft S. In addition, a shuttle A is disposed at the end part distant from the hook shaft S, and a shuttle bobbin case mount C is housed in the opening Ba of the shuttle mount B. The shuttle A is constituted of a circular rotating hook open at the front and rear and a circular shuttle body rotatably supported in the rotating hook. Then a shuttle bobbin case D integrating a bobbin-thread bobbin E is housed in the shuttle body of the shuttle A in this way through the opening part Ba of the shuttle mount B.
