An inner lever (1) for a switchable finger lever (2) of a valve train of an internal combustion engine is provided, having a box-like main part (5) with two lateral walls (6), which are connected at a first end (7) by a transverse bar (8), which intrinsically includes a driver surface (9) for a coupling slide that can be guided longitudinally by the outer lever (3), and opposite from the first end (7), the lateral walls (6) have two strongly crimped together, thin-walled arms (10), which each extend in the direction toward the second end (11) of the inner lever (1) to form a longitudinal bar (12). The arms contact each other with their inner sides (15), and between the lateral walls (6), a cam contact surface (16) can be provided. The inner lever (1) made from thin-walled steel sheet metal at least to a large extent using punch-bending techniques.
An inner lever for a switchable cam follower of a valve train of an internal combustion engine, which can be arranged so that it can pivot relative to an outer lever in a longitudinal recess of the outer lever, the inner lever comprising a main part with two opposing, upright, thin-walled lateral walls, which are connected at a first end by an upright, thin-walled transverse bar, which includes a driver surface thereon for a coupling slide that can be driven longitudinally by the outer lever, and opposite from the first end the opposing, upright, thin-walled lateral walls have two strongly crimped together, upright, thin-walled arms, which extend in a direction toward a second end of the inner lever, opposite the first end, and form upright, thin-walled longitudinal bars with aligned openings for a shaft for the pivoting connection to the outer lever, the upright, thin-walled longitudinal bars contact each other at inner sides thereof, a cam contact surface is located between the opposing, upright, thin-walled lateral walls, and the inner lever made from steel sheet metal is formed using punch-bending techniques.
