The first clutch (5a, 5b) and a second clutch (10, 11) are designed and adapted to each other such that at any time during operation either the first clutch (5a, 5b) rotationally couples the dose setting member (3) and the drive member (4) and / or the second clutch (10, 11) rotationally couples the drive member (4) and the first clicker component (6'). Further, the invention refers to an injection device with such a dose setting mechanism.
