A weight measuring device includes a force measuring cell formed of a Roberval mechanism having a movable pole, a fixed pole, and two parallel beams connecting the movable pole and the fixed pole. At least one of the movable pole and the fixed pole has a plurality of holes formed in a thickness direction thereof. Adaptors are attached to two sides of the one of the movable pole and the fixed pole in the thickness direction. Bolts pass through the holes and the adaptors and are tightened with nuts. At least one of the bolts passes thorough the hole in a direction opposite to that of the other of the bolts. A receptacle plate is attached to the movable pole for supporting a plate for placing the weight thereon.
