The stop (10) has a bearing (12) comprising an upper washer (14) and a lower washer (16), where the washers define raceways (14.1, 16.1). An annular deflector (32) is made of plastic material, and comprises a skirt (32.2) that forms an inner face arranged opposite to a lower support (20) made of plastic material, where static friction coefficient of plastic material of the deflector is lower than static friction coefficient of plastic material of the lower support. A filtering block (24) is provided with an interface (28), and the deflector is provided with an elastic fixing hook (32.3). |
