    摘要: Protective screen (20) mounted on an outer cylindrical surface (9) of a constant-velocity joint (3) and facing towards a sealing device (12) of a rolling-contact bearing (5) which is angularly coupled to the constant-velocity joint (3) for protecting the sealing device (12) and the rolling-contact bearing (5) from the action of external agents; the screen (20) being provided with:
    - an annular wall (21), which is transverse to an axis (A) of rotation of the constant-velocity joint (3) and is arranged in axial abutment against a side wall (11) of said constant-velocity joint (3),
    - a central hole (22), which is made through the annular wall (21) and through which a shaft (10) of the constant-velocity joint (3) passes with play, and
    - a plurality of elastic mounting and centring fins (23), which are distributed uniformly about the central hole (22) and extend unsupported from the annular wall (21) such that they are coupled to the outer cylindrical surface (9) of the constant-velocity joint (3).
