Claims

[Scope of utility model registration request]

(1) In a horizontal hook having an outer hook 10 that rotates around a fixed axis perpendicular to the amount of sewing work, and an inner hook 20 supported in the outer hook 10, the inner hook 20 is exposed from the outer hook 10. A first magnet 46 embedded in the outer periphery of the outer hook 10 generates a magnetic force in a direction opposite to the rotational direction of the outer hook 10.
a second magnet 48 disposed on the sewing machine frame 38 and/or a support plate 40 attached to the sewing machine frame 38, facing the first magnet 46 so as to act on the sewing machine frame 38; A recess 32 is formed in the inner hook 20 to face a fixed locking protrusion 34, and the recess 32 opens in the opposite direction to the rotation direction of the outer hook 10 and rotates in the rotation direction. The locking protrusion 3 on the side
4, and when the locking protrusion 34 and the raised surface 36 come into contact, a gap is formed between the two magnets 46 and 48 for thread removal. A rotation prevention device for the inner pot.

(2) The inner pot rotation prevention device according to claim 1, wherein the first magnet 46 and the second magnet 48 are arranged so that a repulsive force acts between them.
