Claim:
A shift securing device for a multi-speed manual gearbox that is shifted by a selector shaft ( 14 ) disposed axially parallel to a plurality of gearbox shafts ( 2 , 3 , 5 ), the selector shaft being supported so as to be axially movable along and rotatable about a longitudinal axis of the selector shaft and being selectively coupleable to at least one shift fork ( 7 , 9 ) that is guided on at least one of a shift rail ( 6 , 8 ) and one shift rocker ( 11 , 13 ) by an associated shift finger ( 16 , 17 , 18 , 19 ), a locking body ( 26 ), which is rigidly locked to a housing in an axial direction and rotatable with the selector shaft ( 14 ), locking elements ( 42 , 43 , 44 , 45 ) are arranged on the locking body for form-locking either the shift fork ( 7 , 9 ) or the shift rocker ( 11 , 13 ) that is not coupled, the locking body ( 26 ) being a box frame ( 27 ) having at least two transverse members ( 28 , 29 ) and two longitudinal members ( 30 , 31 ), the locking body having respective bearing holes ( 32 , 33 ) disposed in the transverse members ( 28 , 29 ), the bearing holes accommodating the selector shaft ( 14 ) in an axially movable manner, the locking body being connected to the selector shaft ( 14 ) in a rotationally fixed manner by a carrier that engages in one of the longitudinal members ( 30 ) in a circumferentially form-locking manner, the locking body being rigidly locked to the housing by an axial bearing ( 36 ) disposed on one of the transverse members ( 28 ), the transverse members ( 28 , 29 ) and the longitudinal members ( 30 , 31 ), of the locking body ( 26 ), being pressed sheet metal parts and stamped sheet metal parts rigidly connected to one another and the transverse members ( 28 , 29 ) and the longitudinal members ( 30 , 31 ) of the locking body ( 26 ) being either one of welded to one another or inserted and press fit into each other at ends thereof.
