A medicament delivery member module for a medicament delivery device, the medicament delivery member module comprising a proximal shield, a distal shield and a medicament delivery member hub, the medicament delivery member module extending along a longitudinal axis in an axial direction from a proximal end to a distal end, wherein the proximal shield comprises a first surface facing towards the longitudinal axis and a second surface facing away from the longitudinal axis, wherein the medicament delivery member hub comprises a third surface facing away from the longitudinal axis and the distal shield comprises a fourth surface facing towards the longitudinal axis, wherein the proximal shield is moveable in the axial direction relative to the distal shield from a proximal position to a distal position, wherein the medicament delivery member module is arranged so that in a first part of a movement of the proximal shield from the proximal position to the distal position, the first surface and the third surface are in contact with one another and the second surface and the fourth surface are in contact with one another, and the friction between the first surface and the third surface is greater than the friction between the second surface and the fourth surface, so that during the first part of the movement of the proximal shield from the proximal position to the distal position, the medicament delivery member hub moves with the proximal shield, wherein the medicament delivery member module is arranged so that in a subsequent part of the movement of the proximal shield from the proximal position to the distal position, the first surface and the third surface are in contact with one another and the second surface and the fourth surface are spaced apart from one another, and the medicament delivery member hub is restricted from further movement in the distal direction, so that the proximal shield moves in the distal direction relative to both the distal shield and the medicament delivery member hub during the subsequent part of the movement of the proximal shield from the proximal position to the distal position. wherein the proximal shield comprises a first surface facing towards the longitudinal axis and a second surface facing away from the longitudinal axis, wherein the medicament delivery member hub comprises a third surface facing away from the longitudinal axis and the distal shield comprises a fourth surface facing towards the longitudinal axis, wherein the proximal shield is moveable in the axial direction relative to the distal shield from a proximal position to a distal position, wherein the medicament delivery member module is arranged so that in a first part of a movement of the proximal shield from the proximal position to the distal position, the first surface and the third surface are in contact with one another and the second surface and the fourth surface are in contact with one another, and the friction between the first surface and the third surface is greater than the friction between the second surface and the fourth surface, so that during the first part of the movement of the proximal shield from the proximal position to the distal position, the medicament delivery member hub moves with the proximal shield, the first surface and the third surface are in contact with one another and the second surface and the fourth surface are in contact with one another, and the friction between the first surface and the third surface is greater than the friction between the second surface and the fourth surface, so that during the first part of the movement of the proximal shield from the proximal position to the distal position, the medicament delivery member hub moves with the proximal shield, wherein the medicament delivery member module is arranged so that in a subsequent part of the movement of the proximal shield from the proximal position to the distal position, the first surface and the third surface are in contact with one another and the second surface and the fourth surface are spaced apart from one another, and the medicament delivery member hub is restricted from further movement in the distal direction, so that the proximal shield moves in the distal direction relative to both the distal shield and the medicament delivery member hub during the subsequent part of the movement of the proximal shield from the proximal position to the distal position. the first surface and the third surface are in contact with one another and the second surface and the fourth surface are spaced apart from one another, and the medicament delivery member hub is restricted from further movement in the distal direction, so that the proximal shield moves in the distal direction relative to both the distal shield and the medicament delivery member hub during the subsequent part of the movement of the proximal shield from the proximal position to the distal position.
