Abstract
A drive mechanism for an injection device for setting and dispensing of a dose of a medicament includes an inner body fixable inside a housing of the injection device, the inner body including an elongated shaft extending in an axial direction. The elongated shaft includes an outer thread and a blocking structure on an outer circumference. The drive mechanism includes a tubular-shaped display member having an inner thread engaged with the outer thread of the inner body, a dose member axially displaceable between a dose setting position and a dose dispensing position relative to the inner body, and a blocking sleeve axially fixed to the dose member, rotationally fixed to the display member and including at least one blocking element to axially engage with the blocking structure to block an axial displacement of the dose member from the dose setting position towards the dose dispensing position.
