Abstract
A tappet () for a high-pressure fuel pump having a housing (), the drive input side (), which serves as a cam run-on face. The housing () incorporates a roller (), wherein the drive output side (), which serves as a contact surface for a tappet follower part, of said housing () bears against an underside () of a bridge piece () which projects through an inner casing () of the housing (), and a rotation prevention device () which projects beyond the outer casing () of the housing () extends in a window () of the housing (). The rotation prevention device () is formed by a radial elongation of the bridge piece (). A projection extends from the inner casing () of the tappet () only on a portion situated diametrically opposite the window (), which projection is integrally connected and is produced by a punching and embossing process and rises in a wedge shape in a direction of the drive input side. The section () of the sheet-steel bridge piece () which is situated diametrically opposite the radial elongation () is snapped over the projection (), and this section () rests with an edge region () of the underside () thereof on said projection ().
