Abstract

A roller tappet having a housing near whose drive side front end, two diametrically opposing flats receding from an outer wall of the housing are arranged, each of the two flats having a seat with a U-shape open in a direction towards the drive side front end. A pin is mounted in the seats, a roller serving as a run-on surface of a periodic stroke producer extends on said pin, and a support for a tappet follower element is seated axially under the roller near a driven side front end of the roller tappet. A retention element is provided for the pin in an axial direction of the pin and a retention element in the seats of the pin is provided for preventing the pin from exiting axially out of the housing, and these two retention elements are united.
