Improvements in steering swivel carrier parts for vehicles, consisting of a cylindrical metallic housing (9) open at both bases, and with the edge (11) of one of them being weakened into a bevel in order to facilitate the riveting of an internal elastic piece (1) with opening of diameter slightly less than that of the swivel, edges (3) shaped into rounded lips and with a peripheral channel (4) that increases flexibility. The zone (6) opposite the opening of this elastic piece has a hollow collar (5) with surrounding spherical zones of lesser thickness that increase the flexibility of the assembly. The base of this collar (5) has specially arranged slits (7) to provide an exit for air and surplus grease, thereby eliminating the possibility of the enclosed air causing the grease to oxidize and deteriorate. <IMAGE> |
