ABSTRACT:
An accelerometer is disclosed, which includes a flexible hinge, a base table fixed with one end of the flexible hinge, a pendulum fixed to the other end of said flexible hinge, torquers for producing a torque proportional to acceleration applied from the base table to the pendulum and a displacement detecting apparatus for electrically detecting a relative displacement between the fixed portion of the base table and the pendulum, wherein the base table is formed of first and second frames, the first frame is provided with an engagement portion for engaging with the second frame, a fixed portion for the flexible hinge, a fixed portion for the displacement detecting apparatus. In this case, the first frame is provided at its outer peripheral portion with an attaching flange portion and, one plane of the flange portion is used as an attaching reference plane for attaching the accelerometer to a body the acceleration of which is to be measured.
