Rocker arm i.e. roller rocker arm, for variable valve train of combustion piston engine, has bars designed in stepped manner at inner walls, where distance between walls in inner region is less than that between walls in outer region
The arm (1) has a lever body (2) designed as a pressing and punching component made of sheet metal. The lever body has a U-shaped cross-section with parallel side walls (3a, 3b) and a base bar (4) connecting the side walls. Two lateral guide bars (11a, 11b) are provided for lateral guidance of a shaft end of a stroke valve. The lateral guide bars are designed in a stepped manner at inner walls, where distance between the inner walls in an inner region (12) of the guide bars is less than distance between the inner walls in an outer region (15) of the guide bars.
