An accelerator and decelerator sliding block (30), in particular for transport system vehicles, comprising a first plane portion (40) longitudinally elongated, operatively associable to a roller conveyor (11) for accelerating or decelerating a vehicle, and a second portion (38) which extends longitudinally for a longer portion than the first portion (40); the roller conveyor (11) comprises a beam (18) which carries a plurality of axes (20), each carrying in turn a roller (22, 24) associable to the sliding block (30) so that first rollers (22) are arranged at free ends of the conveyor (11) and are arranged at a greater distance than that between successive second rollers (24).
