摘要：
An injection device comprises a housing, a dose indicator positioned within the housing and a dose selector operatively connectable to the dose indicator. The dose selector and the dose indicator are capable of cooperating with one another to set a dose to be ejected from the injection device. The dose indicator comprises an odometer including: i. a units (218) wheel operatively connected to the dose selector so that rotation of the dose selector also rotates the units wheel, and ii. a tens wheel (219) selectively engageable with the units wheel so that rotation of the units wheel also rotates the tens wheel. The dose indicator further comprises an axially-moveable shuttle lock (222) rotationally locked to the tens wheel and selectively engageable with the units wheel and the housing. The tens wheel is selectively engageable with the units wheel via said shuttle lock and, when the tens wheel is not engaged with the units wheel, the shuttle lock is rotationally locked to the housing.
