Abstract

PURPOSE: To prevent the crack to be caused at the welded part between the cunti- lever and the fixed member, by providing the projection to the cunti-lever and its fixing member and welding the projections.
CONSTITUTION: The strain gauge 220 is fitted at the both sides of the cunti-lever 170 made of material having close line expansion coefficient as it. The projection 230 is formed at the external diameter of the fixed part 190 at one end of the cunti- lever 170. Similarly, the projection 240 is formed at the inner diameter of the cunti- lever fixed member 200. Further, the said projections 230 and 240 are butt and welded. Thus, the stress exerted due to the difference of the line expansion coefficient between the cunti-lever and the lever fixing member at lowered temperature after welding is absorbed with elastic or plastic deformation of the projection to prevent the crack of the welded parts.
