The invention refers to an injection device comprising a housing (10) having a first aperture (11) or window, a dose indicator (120) positioned within the housing (10) and rotatable with respect to the housing (10) during dose setting and during dose dispensing, and a gauge element (110), which is interposed between the housing (10) and the dose indicator (120). The gauge element (110) has a second aperture (111) or window, which is positioned with respect to the first aperture (11) or window of the housing (10) such that at least a part of the dose indicator (120) is visible through the first and second apertures (11, 111) or windows- Further, the gauge element (110) is axially guided within the housing (10) and in threaded engagement with the dose indicator (120) such that rotation of the dose indicator (120) causes an axial displacement of the gauge element (110). The injection device further comprises a resilient member (90) adapted to provide a force necessary for ejecting a dose from the injection device. |
