Abstract: A bucket tappet for an internal combustion engine with overhead camshaft comprises a hollow cylindrical tappet shank made of an aluminum material which is closed at one end by a baseplate made of a steel or hard metal material. A guide bush for accommodating a play-compensating element is arranged inside the tappet shank and is concentric to the longitudinal center axis. In order to obtain a permanent connection between the baseplate and the tappet shank, a steel material carrier element is embedded in the tappet shank and the baseplate is secured by soldering or welding to the carrier element.
