Abstract
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.
