Hook

The invention provides a hook which is capable of improving the quality of zipper teeth rows when zipper teeth rows are manufactured. The hook (1) used for manufacturing spiral zipper teeth rows (e) of zippers through linear monofilaments (f) is composed of a handle part (2) which extends in the shape of a rod and a clamping and hanging part (3) which is connected with the handle part and is bent to be a U shape in the mode of pulling back when observed in the Z-axis direction orthogonal to the extension direction of the handle part. The clamping and hanging part is provided with a root part (5) connected with the handle part, a separating part (7) which separates relative to the root part in the opposite direction, and a bending part (6) which is used for connecting the root part and the separating part and is bent relative to the root part and the separating part; in addition, part of the part combining the separating part and the bending part serves as a winding part (8) for winding monofilaments, and one
