A tappet including a housing having a drive-side annular end face at which two flat sections, recessed in relation to an outer shell of the housing, lie diametrically opposite one another, and a bolt supporting a roller mounted in said sections is provided. A bridge section protrudes through an inner shell of the housing, and the output-side end face of said bridge section acts as a contact point for a tappet follower part, the bridge section lying against undersides of said flat sections and being held by a ring that is arranged in the inner shell, and sits in a groove of the inner shell so as not to protrude radially out of said groove, at least two tabs projecting radially inwards from an upper side of the ring, and the bridge section fixed thereupon in the direction of the output-side annular end face.
