Abstract
The present invention relates to a drive mechanism of a drug delivery device for dispensing of a dose of a medicament, the mechanism comprising: an elongated housing () extending in an axial direction (), a piston rod () to operably engage with a piston () of a cartridge () to displace the piston () in axial distal direction (), a dose setting member () rotatably arranged at a proximal end of the housing () for setting of a dose, a base member () having a proximally extending shaft portion () at least partially enclosed by the dose setting member (), a last dose limiting member () radially disposed between the dose setting member () and the base member () and having at least one radial stop () to limit a rotational displacement of the dose setting member () relative to the base member (), wherein the last dose limiting member () is rotatably locked but axially displaceable to one of the base member () and the dose setting member () and wherein the last dose limiting member () is threadedly engaged with the other one of the base member () and the dose setting member ().
