Summary:A tappet (1) for a high-pressure fuel pump of an internal combustion engine is provided, having a tube-like housing (2), in the case of the drive-side annular face (3) of which two flat sections (5) are indented from an outer lateral surface (4) of the housing (2) lying diametrically opposite one another, in which flats a pin (7) is mounted which supports a roller (6), wherein, axially below the roller (6), an inner lateral surface (8) of the housing (2) is penetrated by a separate bridge piece (9), a driven-side end face (10) of which acts as a rest for a tappet follower part and which bears axially firstly in the direction of the drive-side annular face (3) against undersides (13) of the flat sections (5) and secondly in the direction of an output-side annular face (11) of the housing (2) by way of a securing ring (12) which is fixed on the inner shell (8), wherein the bridge piece (9) is held by the securing ring (12) such that it is clamped axially and radially without play in the housing (2).
