The device (4) has a rolling element (6) e.g. ball, arranged between an inner ring (5) and outer rings (7, 8), and a maintaining cage (11) maintaining regular circumferential spacing of the element. A pretension element (10) is housed in a U-shaped envelope (9). The ring (7) includes an oblique portion (7b) extending radially outward from an inner axial portion (7a). The cage is arranged axially between the rings (7, 8). The cage has a maintaining part for maintaining the elements, and an annular bead for supporting the part radially arranged outside the elements.
