ROLLER TAPPET FOR A FUEL PUMP

A roller tappet for a fuel pump includes an integral and hollow-walled guide housing, which has a drive-side edge that encloses a roller mounted on a pin. The ends of the pin are seated in openings in arranged in indented flat surfaces that originate from the drive-side edge and are diametrically opposite each other. An output-side edge of the guide housing has a bridge piece that extends continuously from an inner wall of the one of the flat surfaces to an inner wall of the other flat surface. The bridge piece projects beyond the inner wall towards the outer wall of the particular flat surface, and the output-side outer face of the bridge piece has a contact surface for a pump piston. The flat surfaces are completely continuous from the drive-side edge to the output-side edge of the guide housing.
