摘要：
The present disclosure is generally directed to a clicker arrangement for use in a drug delivery device, i.e. a handheld injection device for selecting and dispensing a number of user variable doses of a medicament. The clicker arrangement comprises a first element rotatable at least in a first direction and a second, non-rotatable element. The first element is axially displaceable relative to the second element between a first position and a second position. One of the elements comprises a clicker arm and the other comprises a protrusion wherein upon rotation of the first element in the first direction relative to the second element the clicker arm is elastically deflectable in a radial direction by the protrusion and relaxable in the opposite radial direction upon disengagement with the protrusion thereby generating an audible and/or tactile feedback signal.
