Sub-assembly of a medicament delivery device with rotatable cap

A sub-assembly of a medicament delivery device, the sub-assembly comprising:

• a delivery member cover;
• a rotator;
• and
• a cap,
• wherein the delivery member cover comprises a tubular proximal portion and a distal portion extending from the tubular proximal portion in a direction of a longitudinal axis,
• wherein the tubular proximal portion comprises a first radially directed surface facing in a circumferential direction around the longitudinal axis,
• wherein the distal portion comprises a second radially directed surface facing in the circumferential direction around the longitudinal axis;
• wherein the rotator comprises a body having a radially directed surface adjacent to the second radially directed surface of the delivery member cover
• wherein the cap comprises a cap body releasably covering a proximal end of the tubular proximal portion of the delivery member cover,
• wherein the cap body comprises a user-accessible surface and a radially directed surface, and
• wherein the radially directed surface adjacent is to the first radially directed surface of the delivery member cover when the cap is operably attached to the delivery member cover such that when a user of the medicament delivery device rotates the cap via the user-accessible surface around the longitudinal axis, the delivery member cover and the rotator are rotated around the longitudinal axis.
