The present invention relates to a drug delivery device as a whole increases Cleveland generating unit (clicker arrangement) and for drug delivery devices, including those parts of Cleveland larger configuration. And a possible element (110), wherein the configuration unit comprises: a first rotatable element 60 and the second rotation. The first element 60 and the second element 110, one is Cleveland Kerr includes arm 67, and the other one of the first element 60 and the second element (110) of the cam (117 ) a. The first element 60 and the second element 110 and the Cleveland large arm (67) can be elastically deformed by the cam 117 to rotate relative, released, the engagement of the cam 117, Cleveland Kerr By arm (67) allows the subject to relax and generates an audible and / or tactile feedback signals. The configuring unit Clichy large arm (67) interacting with the third-axis direction with the lamp 47 in order to - in further comprising: a movable element (40), the third element of the first shaft 40 position when lamp 47 is increased Clichy arm 67 does not interact with, and consequently large Clichy arm 67 is prevented from being in contact with the cam 117; When the third element 40 is in the second axial position, the lamp 47 is brought into contact with the forward cleaners increased by the arm 67, Cleveland large arm 67, the cam 117.
