Abstract
A tappet for a valve train or a pump drive particularly a cup tappet () having a hollow cylindrical outer body on whose wall region () an anti-rotation element () is received in a window-type through-opening (), the anti-rotation element () being seated through support surfaces () of a head () on an outer diameter () of the wall region () and extending with a shank () projecting from the head () through said through-opening (). The anti-rotation element () is fixed via a welded joint. In order to fix the anti-rotation element () with low manufacturing costs and, at the same time, with only an insignificant impairment of the outer body, the welded joint is made between the shank of the anti-rotation element () and an inner body that is received in the outer body and is connected to the outer body. A method of making a tappet of the aforesaid tappet is also provided.
