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 said 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 said dose drum 40 and said stop member 90, relative to the tubular member 10, corresponding to said predetermined length.
