Abstract
A drive mechanism for a medicament delivery device is disclosed having a housing with a proximal end and a distal end, a container carrier arranged within the housing and being axially movable in relation to the housing, and a drive assembly partially arranged within the housing and being axially movable in relation to the housing. The drive assembly has a proximally extended rack arm, a cogwheel arranged within the housing and being rotatable but axially fixed in relation to the housing, wherein the cogwheel is selectively coupled to the rack arm through a tangential engagement with a first set of rack teeth or a second set of rack teeth which are arranged on the rack arm and wherein the first set of rack teeth or the second set of rack teeth forces the cogwheel to rotate when the drive assembly is axially moved towards the proximal end in relation to the housing. The cogwheel further has a connecting member configured to connect to a counter connecting member which is arranged on the container carrier; such that a rotational movement of the cogwheel is converted into a linear movement of the container carrier.
