According to the present invention, it is possible to produce an article-fixing device at low cost and in large quantity and also to drive a pin unit in accurate and assured manner, and to firmly mount an object to be fixed. The article-fixing device comprises a pin unit and a washer combined together for supporting an object to be fixed, whereby the pin unit is designed in flat shape and formed by punching a metal plate, has logs in shape of a fork and is extending from a head of the pin unit, and tips of the legs are tapered and spread out, and the washer comprises a pair of guide gaps arranged at opposed positions and for guiding operation to drive the forked legs and for maintaining an angle of driving at a constant angle, the forked legs inserted into the guide gaps are spread out between the pair of guide gaps, and a support base provided between the pair of guide gaps and used for spreading the forked legs inserted into the guide gaps and for maintaining spreading condition of the forked portion of the pin unit.
L'élément de fixation d'article peut être fabriqué économiquement et en grandes quantités, il permet à un corps de goupille d'être enfoncé de manière fiable et, en plus il permet de fixer l'article. Cet élément de fixation d'article soutient l'article à fixer par une combinaison de corps de goupille et de rondelle. Le corps de goupille a une forme plate obtenue par découpage d'une plaque métallique à l'emporte-pièce et il a deux pattes divergentes partant d'une portion de tête. Les extrémités distales des deux pattes sont pointées et orientées dans des directions mutuellement opposées. La rondelle a une paire de rainures de guidage opposées, pour guider les pattes divergentes lorsque les pattes sont enfoncées et pour maintenir l'angle de pénétration constant, ainsi qu'une portion de siège qui est prévue entre la paire de rainures de guidage et qui est capable d'écarter les pattes divergentes à insérer dans les rainures de guidage respectives et de maintenir les pattes écartées à la portion de bifurcation du corps de la goupille.
