Abstract
A tappet made of light metal comprises a ceiled cylindrical tappet body made of light metal, and a cam receiving plate made of hard metal which has the same outer diameter as that of the tappet body, and which is provided at its outer peripheral edge with a sharp annular piece, the cam receiving plate being integrally coupled to the tappet body by causing the annular piece to bite into the top surface and welding the annular piece and the top surface. With this structure, the tappet body and the cam receiving plate made of different materials can be bonded strongly.
