ABSTRACT:
Two thin walled strain generating areas are provided in each of upper and lower two beams provided between a fixed rigid body and a movable rigid body. The strain generating area of the upper beam is adapted to have a convex-shaped cross section such that the neutral plane which develops no strain in response to a bending moment acting on the strain generating area is spaced from the top surface by a distance unequal to that from the bottom surface. In addition, a strain detecting element is provided on the top surface which is more remote from the neutral plane than the bottom surface.
