The present invention relates to a medicament delivery device comprising a housing (10, 12), which housing (10, 12) is arranged to accommodate a medicament container (20), which medicament container (20) comprises a medicament delivery member (134); a power unit (74) interactively connected to the housing comprises a force element (82) and a plunger rod (76) which is arranged to, upon activation, move linearly in the proximal direction and act on said medicament container (20) for expelling a dose of medicament through said medicament delivery member (134); and a holding member (56) connected to said power unit and to said container holder. The invention is characterised in that the plunger rod comprises at least one first guide-and-stop element configured to interact with at least one second guide-and-stop element on said a holding member for limiting the linear distance the plunger rod (76) is capable of moving during expelling of medicament and which distance corresponds to a dose volume. |
