Abstract
A tappet (), either for a high-pressure fuel pump or for a valve train of an internal combustion engine, with a housing () whose driven side () used for a contact of a tappet-following part forms a contact on a bottom side () of a bridge part () projecting through an inner casing () of the housing (). An anti-rotation locking device () projects past the outer casing () of the housing with a first cylinder section () and sits in a window () of the housing (), with this anti-rotation locking device () being provided as a cylindrical element, and tab-like projections () project from peripheral walls () of the window () and the anti-rotation locking device (), standing 'loose' in the window (), snaps behind these projections. A second cylinder section () of the anti-rotation locking device extends behind the inner casing () of the housing (), and the bridge part (), extending on an axial section of the anti-rotation locking device (), has in its peripheral section a recess () in its outer surface (), with the second cylinder section () of the anti-rotation locking device () being supported against this recess.
