Abstract

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.
