摘要：
An assembly for a drug delivery device (1) is provided, comprising a housing (2), a rotation member (17) adapted and arranged to be rotated in a first and in a second rotational direction with respect to the housing (2) in an operational mode of the assembly, a drive member (16) which is configured to mechanically cooperate with the rotation member (17) such that the drive member (16) follows rotation of the rotation member (17) when the rotation member (17) is rotated in the second rotational direction and such that the rotation member (17) rotates with respect to the drive member (16) when the rotation member (17) is rotated in the first rotational direction, and a piston rod (12). The assembly further comprises at least one biasing member (27) which is adapted and arranged to provide a force tending to bring the rotation member (17) and the drive member (16) out of mechanical cooperation in the operational mode. The assembly is switchable from the operational mode into a reset mode. For switching from the operational mode into the reset mode, the biasing member (27) is configured to drive a relative axial movement between the drive member (16) and the rotation member (17) such that the rotation member (17) and the drive member (16) are brought out of mechanical cooperation. Furthermore, a drug delivery device (1) is provided.Linvention porte sur un ensemble pour un dispositif (1) dadministration de médicaments, lequel ensemble comprend un boîtier (2), un élément de rotation (17) conçu et agencé pour tourner dans une première et une seconde direction de rotation par rapport au boîtier (2) dans un mode fonctionnel de lensemble, un élément dentraînement (16) qui est configuré pour coopérer mécaniquement avec lélément de rotation (17), de telle sorte que lélément dentraînement (16) suit une rotation de lélément de rotation (17) lorsque lélément de rotation (17) tourne dans la seconde direction de rotation, et de telle sorte que lélément de rotation (17) tourne par ra
