Claims

[Scope of claim for utility model registration] In the horizontal hook of a sewing machine, a transparent part and an opaque part are provided on the flange of the bobbin thread bobbin to visually confirm the appropriate amount of bobbin thread remaining, and the opaque part prevents friction with the inner hook. The structure of a bobbin thread bobbin for a horizontal hook is characterized in that the bobbin thread bobbin is prevented from idling by force. 2. The structure of a bobbin thread bobbin for a horizontal hook according to claim 1, wherein the opaque portion of the bobbin thread bobbin is textured to increase a coefficient of friction with the inner hook. 2. The structure of a bobbin thread bobbin for a horizontal hook according to claim 1, wherein a paint is applied to the opaque portion of the bobbin thread bobbin to increase a coefficient of friction with the inner hook. In the horizontal hook of a sewing machine, a magnetic material is provided at the bottom of the inner hook of the horizontal hook, and the magnetic force with the magnet provided on the outer hook prevents the inner hook from moving. A transparent part and an opaque part are provided in order to visually check the appropriate amount remaining, and fine magnetic powder is applied to the opaque part, and the attraction force with the magnetic material at the bottom of the inner hook provides braking force to the bobbin thread bobbin. The structure of the bobbin thread bobbin of the horizontal hook. A horizontal hook bobbin thread bobbin according to claim 1, wherein fine powder of a magnetic material is applied to an opaque portion of the bobbin thread bobbin, and a braking force is applied to the bobbin thread bobbin by an attractive force with a magnet of the outer hook. structure.
