Abstract
An injection device comprising a housing () and a dose selector () to set a dose of medicament to be ejected from the injection device. A spring () coupled to the dose selector stores energy necessary for ejecting the dose from the injection device. A ratchet () arrangement is provided to rotationally couple a ratchet component and an internal surface of the housing in a coupled state and to allow relative rotation between the ratchet component and the internal surface of the housing in an uncoupled state. An over-torque feature () located between the dose selector and the spring is actuatable, when the rotation of the dose selector causes the charging force to exceed a defined limit, to reduce the charging force transferred from the dose selector to the spring. Both the ratchet component and the over-torque feature are provided on a single component ().
