Abstract: A drive assembly suitable for a medication delivery device comprises a housing, a drive member, a piston rod, a rotation sleeve, a guide member and a biasing member. The rotation sleeve is arranged to be displaced in a distal direction when the drive member is displaced in the distal direction by mechanical interaction of the drive member and the rotation sleeve with the rotation sleeve and the drive member both being guided axially by the at guide member. The biasing member exerts a force on the rotation sleeve acting in the proximal direction, said force being transformed into a rotational movement of the rotation sleeve. The rotational movement of the rotation sleeve being transformed into a rotational movement of the piston rod.
