FORCE SENSOR

摘要

A force sensor (1) has a structure body (11) provided with a beam (2) having a cruciform in a plan view and with a projection (3) projecting from the center of the beam (2). The structure body (11) is made, for example, from stainless steel. The four ends of the beam (2) are individually rotatably connected to elastic beams (4). The elastic beams (4) are made, for example, from duralumin. In the lower end of each elastic beam (4) and in each end of the beam (2) are formed through-holes, shafts are inserted in the holes, and the resultant assembly is received in a housing (5). Four fixation sections are arranged inside the housing (5), and the elastic beams (4) are individually rotatably fixed to the fixation sections. Through-holes are formed in the upper end and projection of each elastic beam (4), and shafts are inserted in the through-holes.
