A guide rail ( 1, 22 ) for valve tappets ( 2 ) of an internal combustion engine is provided. The guide rail ( 1, 22 ) has receptacle spaces ( 4 ), which are each used for receiving one of the valve tappets ( 2 ) and in which there are flattened sections ( 6 ) interacting in a positive-fit connection with key surfaces ( 7 ) of the valve tappets ( 2 ), such that each of the valve tappets ( 2 ) is protected from rotating about its longitudinal axis, with the flattened sections ( 6 ) permitting alignment of the valve tappet ( 2 ) parallel to the flattened sections ( 6 ). Here, the guide rail ( 1, 22 ) is formed as a metal carrier ( 3, 25 ) and rotational protection elements ( 8, 9, 23 ), which are fixed on this carrier, have the flattened sections ( 6 ) which also permit alignment of the valve tappet ( 2 ) orthogonal to the flattened sections ( 6 ), in that each flattened section ( 6 ) belonging to one of the receptacle spaces ( 4 ) can be displaced relative to the metal carrier ( 3, 25 ).
