PROBLEM TO BE SOLVED: To provide an engaging/disengaging hook having convenient function of post-fitting engaging/disengaging for taking a supporting line into a helical ring through a rotary guidance and a stable supporting force and having a helical ring structure not damaging the supporting line.SOLUTION: There is provided a post-fitting spiral engaging/disengaging hook made such that several helical winding bodies B formed by bending an elastic hard wire F are inverted back at an optional midway position to form the same number of inverted helical windings C, a symmetrical helical structure G is formed while its bending-back part being set at its central part, a central bending-back top point E is bent in an outer direction of helical circle in such a way that it shows the same direction as an extending direction of supporting axes A at both right and left ends, raised up to a prescribed height, its extremity end is curved in a direction opposite to a helical circulating direction, the supporting axes A at both right and left ends of the helical structure G are fixed to an object element to be hung. |
