摘要：
The present invention relates to a pen type drug delivery device having a dose setting limiter mechanism. The mechanism comprises a housing (10, 30, 40； 40′), a dose setting member (50), which during dose setting rotates relative to the housing (10, 30, 40； 40′) in a first direction and which during dose dispensing rotates relative to the housing (10, 30, 40； 40′) in a second opposite direction, and a limiting element (60) limiting the rotational movement of the dose setting member between a zero dose position and a maximum dose position. The limiting element (60) is rotationally constrained but axially displaceable relative to one of the housing (10, 30, 40； 40′) or the dose setting member (50) and is movable helically (53) relative to the other of the housing (10, 30, 40； 40′)or the dose setting member (50). These movements have end stops (54, 55) limiting the relative movement of the limiting element (60) and thus the dose setting member.
