Abstract:
Elastic support part (3) and weight detection unit (4) having weight detection element (9) are disposed between support stage (1) for supporting a load and load-receiving stage (2) for receiving a load in such a manner as to share and support the load exerted by load-receiving stage (2). Weight detection element (9) is an element for converting an elastic deviation to a load value. Spring constant Km of weight detection element (9) and spring constant Kn of elastic support part (3) are set to Km >> Kn. Furthermore, elastic support part (3) is provided with regulator part (8) that gives a flection amount of a preload according to a predetermined weight but does not regulate flection in a load direction of a load greater than the preload according to the predetermined weight.
