摘要：
A drive assembly (70) for a drug delivery device (1) comprises a rotation member (21) being configured to be rotated in a first direction (44) during setting of a dose of a drug and to be rotated in a second direction (47) during delivery of the dose, a drive component (20) being configured to follow rotational movement of the rotation member (21) in the second direction (47) during delivery of the dose and a stop member (26) being configured to prevent rotational movement of the drive component (20) in the first direction (44). The drive component (20) comprises a first drive part (71) and a second drive part (72), coupled to each other such that relative rotational movement of the first and second drive parts (71, 72) is prevented and relative axial movement is permitted.
