The present invention relates to a medicament delivery device comprising a housing (10,12), capable of containing a medicament container (14), a plunger rod (18) and a drive member (34) arranged to said plunger rod and capable of acting on said plunger rod (18) for moving it in the proximal direction of the device for expelling a dose of medicament from said medicament container (14), a dose and drive setting mechanism (52) comprising a dose setting member (56) operably connected to a force member (82) such that setting of a dose causes said force member (82) to be energized. The intermediate member (68) is configured to interact with a dose setting sleeve (50) through a first unidirectional connection (64, 62), configured to interact with said drive member (34) through a second unidirectional connection (70, 72), and configured to interact with a dose drive sleeve (76) through a third connection (74,78).
