ABSTRACT:
In a tappet structure in which a rotary movement is transformed into an axial movement by way of a cam, the tappet structure has a metallic tappet body, an inside of which has a hollow portion in a manner to have an opening at one end of the tappet body. A friction-resistant ceramic plate is integrally fixed to the open end of the tappet body by means of brazing, so that the cam can frictionally slide on the ceramic plate to move the tappet body axially.
