Abstract
A dose setting mechanism for a medicament delivery device, which dose setting mechanism comprises, a tubular member (10) having a longitudinal track (18) of a predetermined length; a dose drum (40), coaxial with the tubular member (10), and being axially and rotationally movable relative to the tubular member (10); a stop member (90), axially movable but rotationally locked relative to the tubular member (10), and further being in an axially slaved connection with the dose drum (40); wherein the stop member (90) comprises a track follower (98) in engagement with the longitudinal track (18), such that rotational movement of the dose drum (40) relative to the tubular member (10) may cause a maximum axial displacement of the dose drum (40) and the stop member(90), relative to the tubular member (10), corresponding to said predetermined length.
