To solve such problems that when an article is a cap-like support-leg fixing component suitable for the lower end part of a support leg of a chair or the like, it is manufactured and sold in such a manner that its inner diameter is slightly larger than the diameter of the lower end part of the support leg of a chair or the like so as to loosen the fitting with the lower end part, therefore, it is highly likely that the cap-like support-leg fixing component suitable for the lower end part of the support leg of a chair or the like slips off when the chair or the like is moved or vertically moved, however, if the fitting is tight, there is a defect that it is difficult to fit or remove the cap-like support-leg fixing component to/from the lower end part of the support leg of a chair or the like.

An article fixing method is configured so that each recessed notch or groove (2) is provided in the peripheral wall of an elastic member, the lower end part of each recessed notch or groove (2) provided in the peripheral wall is internally wound in and turned up upwardly, and consequently, an article is held and fixed by a repulsive force that the lower end part of each recessed notch or groove (2) turned up upwardly is going to return to its original state.
