That is, when the operator lifts the attached portion N of the article and presses it against the cover member side cover portion 30 from the inside to the outside, the cover member 3 is coil spring as in the case of FIG. 6 is rotated outward with the shaft 6 as a fulcrum against the urging force 5 to form a gap between the hook portion 22 and the attached portion N of the articles from the gap as shown in FIG. Will move outside. The cover member 3 is rotated to the original closed position by the biasing force of the coil spring 5 via the seat 40 when the attached portion N of the article is separated from the cover portion 30. For this reason, in the hook device 8, as described above, when the articles are attached, when the attachment portion N of the articles is pressed against the cover portion 30 from the outside, the cover member 3 moves in the pushing direction in the coil spring 5 and the seat. Since it moves so that it can return through contact | abutting of 32 and the seat 40, the to-be-attached part N of articles | goods can be attached to the hook part 22 by one hand and one-touch operation. At the same time, similarly, when the articles are removed, when the articles are pressed against the cover member side cover portion 30 from the inside, the cover member 3 is pushed in the pushing direction through the contact between the coil spring 5 and the seat 32 and the seat 40. Since it moves so that it can be returned, the attached part N of articles can be removed from the hook part with one hand and one-touch operation. After that, the state shown in FIG. When the hook portion 22 is pushed to the case side, the retracted state shown in FIG. 2 is obtained.
