Abstract

A shift device for a change-speed gearbox, includes a shift rocker having sidewalls for axially displacing a shift sleeve positively connected to a gear wheel clutch or synchronizing unit. A shift finger is fixedly mounted on a shift shaft and positively engages a shift slot of the shift rocker to operate the shift rocker. The shift rocker is of single-piece configuration and made through a non-cutting process, with a blank being pre-punched from a steel sheet, before the blank is shaped into a finished product by at least one bending operation.
