Abstract

An assembly for a drug delivery device (1) is proposed, comprising a housing (13) having a proximal end and a distal end, a dose member (23) which is displaceable in the proximal direction with respect to the housing for setting of a dose of a drug, a clutch member (28) which is displaced in the proximal direction with respect to the housing when setting the dose, and a stop member (30) configured to define a clutch stop position for the proximal displacement of the clutch member with respect to the housing, with the clutch member, when in the clutch stop position, being prevented from further displacement in the proximal direction with respect to the housing,wherein the clutch member and the dose member are configured to mechanically cooperate with one another when the clutch member is in the clutch stop position, thereby preventing further displacement of the dose member in the proximal direction with respect to the housing during setting of the dose. Furthermore, a drug delivery device (1) is proposed.
