PROBLEM TO BE SOLVED: To provide a wrenching hook which has its plug attached to a texture such as a bag, from a rear side of the texture, never slips out of the texture, and therefore is strong and good in appearance. SOLUTION: A plug 1 of a wrenching hook is formed of a main body 4, a knob body 5, and a fixed plate 6. The main body 4 includes a substrate 10, a bearing 11 arranged thereon, which has an elliptic external shape and a circular bore 20 therein, a reduced-diameter portion 12 formed on an upper side of the bearing 11, an enlarged- diameter portion 13 on a lower side of the same, and a projective bar portion 14 consisting of a plurality of projective bars formed on the enlarged-diameter portion 13 and functioning as an engaging portion. The knob body 5 has a divided shaft portion 27 formed on a lower surface of a knob portion 25 in the form of a truncated elliptical cone, whereby the knob body 5 can be rotatably fitted into the bearing 11. The fixed plate 6 includes a bore 32 formed therein, into which the bearing 11 can be inserted, and a hooking portion 37 formed on the periphery of the bore 32, for being hooked on the engaging portion. The plug 1 is attached to a texture by inserting the bearing 11 from a rear side of the texture. When used, the knob body 5 is inserted into a socket attached to a texture of the counterpart, and then the knob portion 25 is rotated, whereby the plug is hooked. |
