PROBLEM TO BE SOLVED: To provide a drive assembly, a drive component of the drive assembly, and a drug delivery device, with which administration of a drug is improved.SOLUTION: A drive assembly 70 for a drug delivery device, comprises: a rotation member 21 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 during delivery of the dose; a drive component 20 configured to follow rotational movement of the rotation member 21 in the second direction during delivery of the dose; and a stop member 26 configured to prevent rotational movement of the drive component in the first direction. The drive component comprises a first drive part and a second drive part, coupled to each other such that relative rotational movement of the first and second drive parts is prevented and relative axial movement is permitted.SELECTED DRAWING: Figure 3 |
