Swivel joint, for example for an anti-roll bar of a wheeled vehicle

The coupling (10) consists of a straight support (20) and an elastically deformable assembly (30) in the form of a laminated structure (35) with alternating hemispherical layers (32, 34) of a supple elastically deformable material such as natural rubber and a more rigid material such as a metal. The layers are pre-compressed by components (40), are fastened together to prevent slip, and held inside sleeves (42, 44) connected by fixings or welded along their adjoining edges (42a, 44a).
