The synchronizing means () and the coupling ring () are arranged coaxially outside the ring gear (). A second member or engagement member () for engaging the coupling ring () and a third member or engagement member () for driving said synchronizing member () are arranged on the external side, as seen radially, of the ring gear (). The coupling ring () is arranged between the synchronizing member () and the first member ().
