Abstract: PURPOSE:To prevent a supporting part from being broken at the time of assembling a movable electrode part by fastening and fixing a movable electrode part in a supporting part by a fastening part, and guide-supporting the movable electrode with a guide part. CONSTITUTION:At assembly time, a movable electrode 23 is fastened and fixed and adjusted easily by using only a fastening screw 36 which is screwed in from one side of upper parts.

IPC: G01G21/24
Filed: 1988-11-28
Abstract: PURPOSE: To reduce weight by forming the ingot of die cast aluminum in a framework structure formed, for example, by through holes. CONSTITUTION: A system carrier 1, guides 4 and 5, and a weight receptor 2 are constituted as a one-piece cast and force corresponding to the mass of an object to be measured is transferred to a relatively short lever arm of a driving lever 3 via a connection element 3 from the weight receptor 2.
