Abstract

A tappet is proposed, for a fuel pump or for a valve timing gear, in each case of an internal combustion engine, comprising a hollow-cylindrical housing, which includes two separate portions lying in line one after the other, which are fitted together in a region of their facing inner faces and are permanently connected to one another by way of a joint. The tappet has a roller on its driving side and an abutment for a follower part on its driven side, which abutment is formed on a separate insert. The abutment is radially supported on the housing in the fitted-together region of the two portions, wherein the insert has a middle annular collar, from which on the one hand a sleeve portion protrudes in the direction of the driving side and on the other hand a dome-like attachment protrudes towards the driven side.
