ABSTRACT:
A tappet in an internal combustion engine comprises a cylindrical body and a cam receiving plate on the top wall of the cylindrical body. To manufacture the tappet by forging, light metal material is provided on the surface which has a groove of the cam receiving plate, and forged in a die to mold the body and to connect the body with the cam receiving plate by a single step, thereby decreasing the number of mechanical steps and cost.
