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: —a housing (), —a piston rod () extending in an axial direction () to operably engage with a piston () of a cartridge (), —a drive sleeve () rotatably supported in the housing (), at least partially enclosing the piston rod (), the drive sleeve () is operably releasable from the piston rod () for setting of a dose and the drive sleeve () is operably engageable with the piston rod () for dispensing of the dose, —a dose limiting member () threadedly engaged with the drive sleeve (), rotatably locked to the housing () and being displaceable in axial direction () in response to a rotation of the drive sleeve () relative to the piston rod (), —at least one stop member () provided on the piston rod () to engage with the dose limiting member () for impeding a further displacement of the drive sleeve () relative to the piston rod (), when a maximum dose configuration has been reached.
