The injection device includes: an elongated housing extending along a longitudinal axis (z) and comprising a sidewall, a dose tracker having a portion arranged inside the housing, the dose tracker comprising at least one tracking stop feature, wherein a positional state of the dose tracker relative to the housing is indicative of a size of the dose, and a preselector comprising a preselector stop feature. Wherein the tracking stop feature and the preselector stop feature are configured to mutually engage and to block a displacement of the dose tracker beyond a predefined maximum dose positional or rotational state. The preselector is at least one of translationally or rotationally displaceable relative to the housing along a displacement path between at least two preselection positional states.
