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&prime；), a dose setting member (50), which during dose setting rotates relative to the housing (10, 30, 40； 40&prime；) in a first direction and which during dose dispensing rotates relative to the housing (10, 30, 40； 40&prime；) 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&prime；) or the dose setting member (50) and is movable helically (53) relative to the other of the housing (10, 30, 40； 40&prime；)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.
