摘要:
A drive assembly for a medication delivery device is provided which is switchable from an operational state to a resetting state and which comprises: a housing having a proximal end and a distal end, a drive member adapted to be rotated with respect to the housing, and a stop member adapted to prevent rotational movement of the drive member in a first direction with respect to the housing and to permit rotational movement of the drive member in a second direction with respect to the housing, the second direction being opposite to the first direction. In the operational state of the drive assembly the stop member is held in engagement with the drive member, and for switching into the resetting state of the drive assembly the stop member is enabled to disengage from the drive member caused by gravity due to the weight of the stop member. Moreover, in the operational state of the drive assembly the drive member may be held in engagement with a rotation member, and for switching into the resetting state of the drive assembly the drive member may be enabled to disengage from the rotation member caused by gravity due to the weight of the drive member.
