Abstract

The fork (10) comprises a pair of legs (16) adapted to sup¬ port for rotation a wheel (18) and a hydraulic braking device including a pair of hydraulic braking actuators (26) , each of which is mounted on a respective leg (16) and is provided with a friction member (38) . Each braking actuator (26) is arranged to press the respective friction member (38) against a braking surface (20a) of the wheel (18) so as to exert a braking force. According to the invention, each leg (16) has, on the side facing the wheel (18) , a side abutment surface (24), a lower support surface (50) and a front stop surface (52), and each hydraulic actuator (26) has an outer side face (28) arranged against the side abutment surface (24), a lower face (32) resting on the lower support surface (50), a front face (34) retained longitudinally by the front stop surface (52) and an inner side face (30) on which the friction member (38) is mounted.
