ABSTRACT:
A hydraulic antivibration support comprises a strength member connected to a plate by an elastomer body whose base is pressed against the plate to define two hydraulic chambers and a narrow channel, all filled with liquid. A perforated insert embedded in the base of the elastomer body has tabs crimped over two opposite reception edges of the plate, which edges form rims projecting away from the perforated insert. Each tab has a free end folded behind the corresponding rim to anchor the tab onto the rim.
