<p>PURPOSE:To provide a sensor low in height with no overload in a strain motive part by constituting a force receiving part of a central shaft part in the strain distortion part and an overhung part protruded to the outward from this shaft part. CONSTITUTION:A force receiving part 3 is constituted of a dish-shaped unit 35 comprising a short shaft part 32 integrally formed with a strain distortion part 10 and a plate-shaped part 34 integrally formed with a cylinder part 33. A shaft part 30 is constituted of the short shaft part 32 and the cylinder part 33, and also constituting an overhung part 31 of the plate-shaped part 34. A erected peripheral part of the plate-shaped part 34 is placed adjacent to an annular part 11, and a press-in amount of the plate-shaped part 34 is restricted by contact with the annular part 11. An electrode part C is provided by plating in a total surface opposed to a cover unit 2 of the strain motive part 10, and four-divided electrode parts Cx+, Cx-, Cy+, Cy- are formed by etching parallelly to the electrode part C. Thus by decreasing height also with no overload acting in the strain distortion part 10, damaging a strain distortion unit 1 can be prevented.</p> |
