Load detecting vibrator

Abstract

Abstract PURPOSE:To improve the working accuracy and the detection accuracy to enhance the mass productivity by working a metallic plate having a prescribed thickness in one direction to constitute a solid part and a vibrating part in one body and providing a through hole near the part connected to this vibrating part and absorbing the bending stress acting upon the vibrating part by a thin part formed with said through hole. CONSTITUTION:Both end parts of thin plate-shaped chords 1a and 1b constituting an oscillating body 1 are connected by connecting parts 5 to constitute an oscillator body 6. This vibrator body 6 is supported by thin plate-shaped supporting parts 7 and 7a extending from connecting parts 5, A through hole 8a parallel with the plate surfaces of supporting parts 7 and 7 and those of chords 1a and 1b is formed on each fixed part 8, and thin parts 8b and 8b are provided, and fixed parts 8 and supporting parts 7 are connected through them. Since the vibrator body 1, supporting parts 7, fixed parts 8, and through holes 8a are worked in the same direction, the working accuracy is improved, and deformation and working stress for working are not generated, and the detection accuracy as a load detecting means is improved, and the mass productivity is improved because there are no complicated reattaching works.
