ABSTRACT:
The supporting body of an instrument is joined to a casing by means of ribs fitting into guideways angularly spaced around a centerline of the supporting body. Thereby, small clearances between the ribs and guideways in a direction parallel to the casing wall surfaces are effective in limiting play at right angles to the casing walls, where much greater clearances must be provided. The casing may expand or shrink freely without exerting strains on the supporting body that could interfere with the proper function of the instrument, due to the large radial clearances between the ribs and guideways.
