摘要:
The present invention relates to a drive mechanism for an injection device for setting and dispensing of a dose of a medicament, the drive mechanism comprising:—a tubular shaped housing component (12, 45) extending in an axial direction (z) and comprising an inner thread (46),—a tubular shaped display member (80) having an outer thread (81) engaged with the inner thread (46), and—a dose member (90) axially displaceable between a dose setting position (S) and a dose dispensing position relative to the display member (80),—wherein the display member (80) comprises at least one blocking member (87) on its outer circumference to axially engage with a blocking structure (18) on an inside facing sidewall portion (12a) of the housing component (12, 45) to block an axial displacement of the dose member (90) from the dose setting position (S) towards the dose dispensing position.
