 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the present invention. In this figure, a hook 1 is made of synthetic resin, and has a hook portion 2, an elastic piece 3, a rotation permitting portion 4A, a rotation restricting portion 4B and a collar. It comprises a part 5. The hook portion 2 is for hooking a hook hole of an object to be hooked, which will be described later, and has a structure in which a rod body having a substantially circular cross section is bent into an L shape, and is also shown in FIG. As shown, grooves 2A, 2A are formed on both sides. The elastic piece 3 shown in FIG. 1 is continuously provided at the base end of the hooking portion 2, and is formed by crossing the axis C of the hooking portion 2 and extending substantially in the shape of an umbrella. It is equipped with 3A and 3A. The rotation allowance portion 4A is for allowing the hook 1 to rotate around the axis C of the hook portion 2, is formed adjacent to the elastic piece 3, and has a circular cross section. ing. The rotation restricting portion 4B serves to restrict the hook 1 from rotating around the axis C of the hook portion 2, and is formed adjacent to the rotation permitting portion 4A, as shown in FIG. It has a square cross section. The collar portion 5 in FIG. 1 is formed adjacent to the rotation restricting portion 4B and facing the elastic piece 3, and has a short axis dimension W1 and a long axis dimension L1 and the hook fixing member 6 shown in FIG. The relationship between the short axis dimension W2 and the long axis dimension L2 of the hook attachment long hole 6A is set to W1 <W2, L1 <L2, and the length L3 of one side of the rotation restricting portion 4B (see FIG. 3) and The outer diameter R (see FIG. 2) of the hook portion 2 is set to the same size as the short axis dimension W1 of the collar portion 5.

With such a configuration, first, the hook portion 2 is grasped by a finger, and the collar portion 5 is shown in phantom lines with respect to the hook attachment elongated hole 6A of the hook fixing member 6 of FIG. After making the insertable posture (sideways), as shown in FIG. 5, the collar portion 5 and the rotation restricting portion 4B are inserted into the hook attachment elongated hole 6A so that the lip portions 3A and 3A of the elastic piece 3 are inserted. The elastic piece 3 is elastically deformed by pressing it against the surface of the hook fixing member 6, and the rotation permitting portion 4A is positioned in the hook attachment elongated hole 6A. Then, the rotation restricting portion is rotated by rotating 90 degrees around the axis C to change the attitude of the collar portion 5 into a non-insertable attitude as shown in FIG. 6 and then loosening the pressing force to the elastic piece 3. 4B is returned to the hook attachment elongated hole 6A side, and the rotation restricting portion 4B is fitted into the hook attachment elongated hole 6A as shown in FIG. As a result, the rotation of the hook 1 around the axis C is restricted, and the elastic force of the elastic piece 3 and the collar 5 cooperate to clamp the hook fixing member 6 so that rattling or looseness does not occur. The attached state of the hook 1 can be obtained. Therefore, as shown by the solid line in FIG. 8, the eyelets 7A provided on the sheet 7 can be hooked on the hooking portion 2 as shown by the phantom line. Incidentally, the removal of the sheet 7 and the hook 1 can be easily carried out by the reverse procedure of the above-mentioned mounting operation as in the mounting operation.

In the above-described embodiment, the bent portion at the tip of the hooking portion 2 is formed so as to largely project. However, the present invention is not limited to such a case, and the tip of the hooking portion 2 is not limited to such a case. The bent portion may be made to project slightly, or a protrusion projecting in a direction intersecting with the linear shaft portion may be formed at the tip end side position of the linear shaft portion of the hooking portion 2. Further, in the above-described embodiment, the length of the elastic piece 3 in the longitudinal direction is shorter than the length of the collar portion 5 in the longitudinal direction. However, in order to increase the elastic force of the elastic piece 3, the elastic piece 3 is formed in the longitudinal direction. The length of the elastic piece 3 may be shorter than the length of the collar portion 5 in the longitudinal direction, and the elastic piece 3 may be formed in an umbrella shape.
