Abstract
A dose setting mechanism for a medicament delivery device is presented having a locking assembly that reliably and consistently unlocks a dose injection button and concurrently a lead screw when the dose setting mechanism is transitioned from a non-activated state to an activated state. This locking assembly uses a rotating plate having a locking protrusion that engages a radial projecting tab on a rotationally fixed plunger rod nut. An alignment member is also presented that prevents rotational drift of a dosing member.
