摘要：
The present invention is generally directed to a dose setting mechanism and a drug delivery device herewith, i.e. a handheld injection device for selecting and dispensing a number of user variable doses of a medicament. The dose setting mechanism comprises a dose setting member (50) rotatable relative to a housing (10, 20) in a first direction for dose setting and in an opposite second direction for dose correcting, a cam ring (150) and a coupling member (70) coupled to a drive member (110). A ramped interface (52, 152) is provided between the dose setting member (50) and the cam ring (150) such that rotation of the dose setting member (50) relative to the cam ring (150) in the second direction causes axial displacement of the cam ring (150).
