ABSTRACT:
A horizontal axis full rotary hook for a sewing machine, including a generally cylindrical hook base having a point of hook, an inner circumferential surface, and a guide groove formed in the inner circumferential surface; and a generally cylindrical bobbin-case holder having an inner circumferential surface, an outer circumferential surface, and a part-circumferential rail provided on the outer circumferential surface, the bobbin-case holder being supported by the hook base such that the bobbin-case holder is freely rotatable relative to the rotary hook while the rail is guided in the guide groove, the bobbin-case holder having a needle aperture which allows a sewing needle with an upper thread to be moved down to a bottom position thereof, the needle aperture having a first inclined inner surface which is opposite to the point of hook with respect to the needle at the bottom position, a distance between the needle at the bottom position and the first inclined inner surface as measured in a direction parallel to a rotation axis of the bobbin-case holder being decreased in a direction from the outer circumferential surface of the bobbin-case holder toward the inner circumferential surface of the bobbin-case holder.
