Abstract

An assembly for a drug delivery device (1), and a drug delivery device, are proposed with a housing (13) having proximal and distal ends. A dose member (23) is displaceable proximally with respect to the housing for setting of a dose of a drug. A clutch member (28) is displaceable proximally with respect to the housing when setting the dose. A stop member (30) is configured to define a clutch stop position for the proximal displacement of the clutch member with respect to the housing, The clutch member, when in the clutch stop position, is prevented from further displacement proximally with respect to the housing, and 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 proximally with respect to the housing during setting of the dose.
