Abstract

The invention concerns a roller tappet (1) for a high pressure fuel pump, said roller tappet (1) comprising a housing (2) comprising on a drive side front end (3), a slide-mounted roller (4) serving as a running surface of a cam, said housing (2), as viewed in housing direction, comprising a bridge member (5) arranged below the roller (4), said bridge member (5) comprising on a front end (7) turned towards a driven side front end (6) of the housing (2), a support (8) for a tappet follower member, wherein a shell member (11) like a semi shell or a one-third shell separated out of a rolling bearing ring is seated in a cylindrical cavity (9) of a further drive side front end (10) of the bridge member (5), and the roller (4) extends for sliding displacement directly in said shell member (11).
