Abstract
An assembly for a drug delivery device includes a guide track and a spring member. A first section of the guide track defines an angular start position for a guide feature of the dose member and a second section of the guide track defines an axial stop position for the guide feature. When the dose member is rotated in a dose setting direction, the guide feature is angularly displaced from the angular start position towards a connection region of the guide track, the spring member is torsionally biased by the spring member towards the angular start position. When the guide feature passes the connection region, the guide feature enters the second section and is axially displaced towards the axial stop position in which reduction of the torsional bias is prevented by mechanical cooperation of the guide feature and the second section.
