A lever for a valve control of a piston engine is provided, which is embodied as a rocker arm, rocker lever or finger lever. A roller ( 6 ) is rotationally mounted on a support pin ( 7 ) in an intermediate space of the lever. The lateral sides ( 1, 2 ) are tapered ( 8, 9, 10, 16 ) in a region of a bore ( 14 ) which receives the support pin ( 7 ), whereby the sum of the widths ( 12, 13 ) of the lateral parts ( 1, 2 ) is smaller than a total width ( 11 ) of the intermediate space ( 5 ) enabling a counter perforation of the bore ( 14 ) to be possible.
