A motor vehicle sun visor (P) has a substantially tubular spring mechanism (R) fitted in its hinge-rod housing for gripping the rod to retain the visor in a desired angular position on the rod in use. The spring mechanism is formed from a single piece of sheet spring metal and is of substantially tubular form with a longitudinal curved wall (1) connected at opposite longitudinal edges to two parallel flat walls (2, 2') which grip the hinge rod in use. The other edges of the flat walls are joined to two curved wall portions whose free edges (6, 6') define an aperture. The curved wall and wall portions are a close fit in the tubular housing (8) with a longitudinal projection (7) thereof fitted in the aperture to prevent relative rotation of the spring mechanism and the housing, and the spring mechanism has outwardly-projecting tabs (5, 5', 5'') which snap engage in a recess (10) in the housing wall to restrain the spring mechanism against axial movement in the housing. |
