The present invention relates to drug delivery and to a drive mechanism for such drug delivery device for dispensing of a dose of a medicament. The drive mechanism comprises: an elongated body (12; 102) extending in an axial direction (1, 2), a piston rod (36; 136) to engage with a piston (114) of a cartridge (112) containing the medicament and being movably disposed in axial direction (1, 2) with respect to the body (12, 102), at least one lever (16; 126) pivotally arranged relative to the body (12; 102), and at least one lever linkage (20; 120) operably engaged with the piston rod (36; 136) and pivotally connected to the lever (16; 126) for transferring a pivoting displacement of the lever (16; 126) into an axial displacement of the piston rod (36; 136). |
