Abstract

The invention concerns a finger lever (1) of a valve train of an internal combustion engine, said finger lever comprising two side walls (3, 4) connected through a transverse portion (2). The finger lever (1) further comprises on one end (6) of an underside (5) of the transverse portion (2), a complementary cavity (7) for a head of a support element and additionally comprises on this one end (6), a reception (8) for a coupling element (8a) for optionally coupling the finger lever (1) to a further lever (9) for achieving different cam lifts. According to the invention, the two portions (7, 8) are made in the form of a single assembled unit as a separate component. This is advantageous from the manufacturing point of view particularly if the levers (1, 9) are made of sheet metal.
