Abstract
An assembly (100) for a drug delivery device is presented. The assembly comprises a housing (10) with a main axis (X), a dose setting member (2) being rotatable with respect to the housing (10) for setting a dose of a drug, an activation member (1) being axially movable with respect to the housing (10) for dispensing the dose from the drug delivery device, and a rotation member (5) being arranged between the activation member (1) and the dose setting member (2). The assembly (100) is configured such that the rotation member (5) is rotatable with respect to the dose setting member (2) and the activation member (1), wherein the outer surface (21) of the assembly (100) comprises the outer surface (22) of the rotation member (5).

An assembly for a drug delivery device, the assembly comprising:
- a housing comprising a main axis;
- a dose setting member being rotatable with respect to the housing for setting a dose of a drug;
- an activation member being axially movable with respect to the housing for dispensing the dose from the drug delivery device;
- and
- a rotation member being arranged between the activation member and the dose setting member, wherein the rotation member is disposed circumferentially surrounding the activation member, wherein the rotation member is rotatable with respect to the dose setting member and the activation member, wherein the rotation member is configured to rotate or axially translate independently from the dose setting member and the activation member, wherein an outer surface of the assembly comprises an outer surface of the rotation member.
A drug delivery device comprising:
- an assembly comprising:
- a housing comprising a main axis;
- a dose setting member being rotatable with respect to the housing for setting a dose of a drug;
- an activation member being axially movable with respect to the housing for dispensing the dose from the drug delivery device;
- and
- a rotation member being arranged between the activation member and the dose setting member, wherein a diameter of the activation member is smaller than a diameter of the rotation member, wherein the rotation member is rotatable with respect to the dose setting member and the activation member, wherein the rotation member is configured to rotate or axially translate independently from the dose setting member and the activation member, wherein an outer surface of the assembly comprises an outer surface of the rotation member.
