A weight measuring device comprising a base fixed to an object, a strain detection substrate fixed to the base, a fitting pin fixed to the strain detection substrate, an arm rotatably attached to the base by a support pin, and a leaf spring with one end fixed to the arm and the other end supported by the fitting pin. The weight measuring device further comprises a second arm with one end receiving the load of the object to be measured and the other end fixed to the arm through a link pin. By the configuration of the present invention, the load applied to the strain detection substrate is reduced, and a weight measuring device improved in detecting resolution is obtained. Furthermore, the weight measuring device of the present invention is unitized, and the weight measuring device can be easily built into various equipment.

L'invention concerne un matériel de mesure de poids, qui comprend un socle fixé à un corps de fixation; un substrat de détection de contrainte fixé au socle; une broche de raccord fixée au substrat de détection de contrainte; un bras articulé au socle par une cheville de support; et une lame ressort dont une extrémité est fixée au bras et l'autre extrémité repose sur la broche de raccord. Le matériel de mesure de poids comprend également un second bras dont une extrémité reçoit la charge d'un objet à mesurer et l'autre extrémité est fixée au bras par un axe de liaison. Grâce à cette disposition, la charge exercée sur le substrat de détection de contrainte est atténuée et on obtient un matériel de mesure de poids présentant une résolution de détection améliorée. De plus, le matériel de mesure de poids peut s'intégrer facilement à divers appareils du fait de son unitisation.
