As shown in the figure, place the thread dividing groove bottom 11 so that the tip 9 side is on the line connecting the rear end 15 of the inner hook 1 and the axis 5a of the center shaft 5 of the inner hook, and insert the upper claw 10.
The upper claw 10 is formed at an angle B toward the direction of the tip 16, and the angle A of the upper claw 10 is changed to an angle C than that of the conventional type without changing the position of the tip 16.
An inner hook of a half-rotation sewing machine, characterized in that the inner hook is set at a reduced angle D.
