The invention relates to a dose setting mechanism (1) for a drug delivery device (2), comprising a number of separate dose setting elements (3.1 to 3.n), wherein a dose volume and/or a dose number are/is set by moving at least one of the respective dose setting elements (3.1 to 3.n) from a stack position (I) to an initial position (II), and wherein a medicament dose volume is applied by moving at least one dose setting element (3.1 to 3.n) from the initial position (II) to a dispense position (III) and wherein the movement of the dose setting element (3.1 to 3.n) from the initial position (II) to the dispense position (III) is limited by at least a height (h) of the dose setting elements (3.1 to 3.n) in the initial position (II), wherein each dose setting element (3.1 to 3.n) comprises a plurality of bulges (B1 to Bm) on at least one surface side (S1), wherein the height (h) of each dose setting element (3.1 to 3.n) equals a sum of the thickness (D) of the dose setting element (3.1 to 3.n) and the bulge height (h1).. |
