Abstract
The present disclosure relates to a drive mechanism for an injection device. The mechanism includes an inner body fixable inside a housing of the injection device and including an elongated shaft extending in an axial direction. The shaft includes an outer thread and a blocking structure on an outer circumference. A tubular-shaped display member has an inner thread engaged with the outer thread of the inner body. A dose member is axially displaceable relative to the inner body or the display member between a dose setting position and a dose dispensing position. A blocking ring is axially engageable with the dose member, rotationally fixed to the display member and includes a blocking element to axially engage with the blocking structure for blocking an axial displacement of the dose member from the dose setting position towards the dose dispensing position.
