Abstract: A strut for MacPherson-type suspensions for motor-vehicles comprises an upper tubular member of sheet metal which forms the cylinder of a telescopic shock absorber, and a sheet metal housing having an upper wall with a circular aperture. An additional reinforcing member of sheet metal is welded to the housing to define a supplementary wall adjacent to the upper wall of the housing. The supplementary wall has a circular aperture, aligned with, and spaced from, the circular aperture of the upper wall. A lower portion of the tubular member is engaged with a close fit into the said two aligned apertures and is fixed by welding to an edge of at least one of the apertures.
