Abstract
A device for assembling a circular stage of pivoting vanes and composed of a ring for retaining bushes in which the pivots of the vanes rotate. The ring is composed of sectors extending between the pivots and connected together by a circular rail. A further ring separate from the rail or integrated with the latter is engaged in throats of the pivots so as to retain them against an axial movement.
