ABSTRACT:
A load cell for use in detecting a load imposed thereon which includes a body (30) in which strain is induced in proportion to the imposed load, and a strain sensor (40) for detecting the strain induced in the body (30). The body (30) is a plate member having a longitudinal axis (X) and the strain sensor (40) is mounted on the body (30). The body (30) has an opening (31) defined therein at a location intermediate of the length of the body (30) so as to define a fixed rigid body forming region (70) at one end thereof, a movable rigid body forming region (71) at the opposite end thereof opposite to the fixed rigid body forming region (70) in the longitudinal direction (X), and side connecting strips (30b, 30b) spaced by the opening (31) from each other in a widthwise direction (Y) of the opening (31) and connecting the fixed rigid body forming region (70) and the movable rigid body forming region (71) together. The strain sensor (40) has opposite ends (41c) spaced in the longitudinal direction (X) and mounted on the body (30) with its opposite ends (41c) fixed to the fixed rigid body forming region (70) and the movable rigid body forming region (71).
