摘要： A cam follower for actuating a gas exchange valve of an internal combustion engine, which has a lifting body cold formed from sheet metal and that forms, on a valve-sided lifting section which has two lateral walls and a first base section connecting the walls, a cross-sectional profile which is open towards the gas exchange valve in a U-shaped manner, and on a joint-sided lifting section that has lateral walls and a second base section connecting the walls, a modifiable cross-sectional profile which is initially open towards the gas exchange valve in a U-shaped manner the U-shape adopting a trough shape that has a protruding annular cavity. The trough shape adjacent to an annular cavity on the side of the valve-sided lifting section is M-shaped and has two free recesses open towards the gas exchange valve and extend respectively between one of the lateral walls and the second base section.
