ABSTRACT:
In a servo accelerometer, a support rod is formed integrally with a pole piece bottom, which is disposed between a magnetic yoke and a magnet. The support rod is extended to penetrate to the outside through a through-hole formed in a closure plate portion of the magnetic yokes. The sensing mechanism is connected via the support rod to a housing by fixing the support rod at the extended end thereof to the housing. The support rod may be formed integrally with the closure plate portion of the magnetic yoke, rather than the pole piece bottom.
