Abstract
The invention relates to a driving device for an injection device for administration of a liquid drug. The driving device has inter alia a rotary member, rotation of which relative to the housing causes a pretensioned spring to move a propulsion member in the dispensing direction, and a coupling which is closed and is opened by pressing of an actuating member, the opened coupling enabling the rotation of the rotary member in a first direction of rotation, and the actuating member being coupled to the rotary member such that pressing of the actuating member causes the rotary member to rotate already when the coupling is still closed.
