Abstract
The present invention relates to an injection device comprising a housing, a resilient member adapted to provide a force in the axial direction of the injection device for ejecting a dose from the injection device. The injection device further comprises a dose setting member operatively connected to a dose indicator barrel positioned within the housing, the dose setting member and the dose indicator barrel being movable relative to each other and cooperating to set the dose to be ejected from the injection device. The dose indicator barrel undergoes, during dose setting, a combined rotational and translational movement within the housing and relative to the housing.
