Abstract
The present invention concerns a drug delivery device () comprising: a housing () extending along a main axis, a torsion spring () comprising a first spring end () arranged stationarily with respect to the housing () and a second spring end () capable of rotation about the main axis, a rotatable shaft () extending along the main axis, the rotatable shaft () having a non-self-locking thread () and being axially fixed with respect to the housing (), a spring end retainer () to which the second spring end () is attached, the spring end retainer () being rotationally fixed relative to the rotatable shaft (), and a nut member () engaged with the non-self-locking thread (), the nut member () being axially movable by translation relative to the housing () to thereby travel the non-self-locking thread () between a first position in which the torsion spring () is in a relaxed state and a second position in which the torsion spring () is in a strained state.
