Abstract

The invention proposes a switchable roller tappet (1) for transmitting a cam lift to a push rod. According to the invention, the inner and the outer rotation-preventing devices of the tappet are made as a single component (17). This component is arranged in a reception (13) of the inner element (4), which reception also serves to lodge a coupling means (24). A tappet (1) of this type can be economically manufactured.
