摘要： A bobbin (40) which is housed in a bobbin case holder (30) is held, as it is elastically pressed by a peripheral wall (60) of a bobbin case (31). Passing through a gap (122) which is created between an outermost portion of a flange (97b) of the bobbin (40) which is disposed on an open end side of the bobbin case holder (30) and an inner peripheral surface of the peripheral wall of the bobbin case (31) and between the flange (97b) of the bobbin (40) which is disposed on the open end side of the bobbin case holder (30) and the inner surface of an end wall of the bobbin case (31), a bobbin thread (62) which is wound around the bobbin (40) is led outside through the bobbin thread leading hole (70) which is formed in the end wall (61) of the bobbin case (31). When the bobbin thread (62) is led out as sewing is started, since the bobbin (40) is held as it is elastically pressed by the peripheral wall (60) of the bobbin case (31) within the bobbin case holder (30), tension force of the bobbin thread (62) prevents the bobbin (40) from getting displaced within the bobbin case holder (30) in an axial line direction, and hence, an inconvenience that the tension force of the bobbin thread (62) varies is avoided, nonuniform fastening of the thread does not result, and the quality of sewing is improved.

摘要： According to the invention, since the axis (L3) of a needle (38) is inclined with respect to an imaginary plane perpendicular to the axis (L2) of a lower shaft (28), the lowermost position of the needle (38) where it comes closest to a loop taker (30) is spaced from the loop taker (30) in the axial direction thereof in proportion to the degree of inclination of the axis (L3) of the needle (38). As a result, the length of a bobbin (61) accommodated in the loop taker (30) can be extended along the axis (L2) thereof, thereby permitting the amount of bobbin thread loaded on the bobbin (61) to be increased. At this time, the amount of needle thread drawn by the needle thread take-up may remain the same as in the previous construction and need not be changed, which serves to eliminate the problems such as thread breaking or difficulty of thread cast-off.
摘要翻译： 根据本发明，由于针（38）的轴线（L3）相对于垂直于下轴（28）的轴线（L2）的虚拟平面倾斜，所以针（38）的最下位置 与针头（38）的轴线（L3）的倾斜度成比例，最接近环形接收器（30）在其轴向方向上与回路接收器（30）间隔开。 结果，容纳在回路接收器（30）中的线轴（61）的长度可以沿其轴线（L2）延伸，从而允许加载在线轴（61）上的底线量增加。 此时，由于上述结构，可以保持与上述结构相同的针线量，不需要改变，这样可以消除螺纹断线等问题。

摘要： In accordance to the invention, because the front section of the loop seizing beak (29) in the rotating direction (A) of the rotating hook is replaceable, the beak (29) can be replaced with a new one when the old one (29) is worn. Also because the replaceable beak is made of a material of high hardness, burr-like rising edges described in relation to the prior art not so easy to occur.
Also in accordance to the invention, because the beak (29) and the loop retaining part catcher (31) which are formed integrally are replaceable, it can be replaced with a new one when the raceway (29) and/or the loop retaining (31) is worn, thereby enabling to obtain good sewing performance for long period of time.摘要翻译： 根据本发明，由于旋转钩的旋转方向（A）上的环状抓钩（29）的前部可更换，所以当旧的（29）可以换成新的（29） ）穿了 此外，由于可更换的喙由高硬度的材料制成，相对于现有技术描述的类似毛刺的上升边缘并不容易发生。 同样根据本发明，由于整体形成的喙（29）和环保持部分捕获器（31）是可更换的，所以当滚道（29）和/或回路保持（ 31），从而能够长时间获得良好的缝制性能。

摘要： A full rotary loop taker assembly comprising a loop taker (11) rotatably held in a loop taker support (1), and a driver (3) for rotatively driving the loop taker as it is rotated around a rotative axis (4) intersecting the rotative axis (12) of the loop taker. The loop taker is formed on its bottom surface wall (16) with at least three angularly spaced engaging holes (17a, 17b, 17c). The driver is formed with at least three angularly spaced projections (10a, 10b, 10c) adapted to be received in the engaging holes. During the rotation of the driver, the projections are successively received in the corresponding engaging holes in such a manner as to ensure that there is always at least one projection which has been received in the corresponding engaging hole. Further, to allow passage of an upper thread loop (23), in a predetermined angular range in the rotation of the driver the respective projections are ready to escape from the corresponding holes.
