| 摘要 |
The present invention relates to a drive mechanism for a drug delivery device, comprising a number of mechanically interacting functional components (18, 20, 22, 26, 28) among which at least a piston rod (18) is adapted to transfer thrust to a piston (16) of a cartridge (8) that contains a medicinal product to be dispensed, wherein at least one of the functional components (18, 20, 22, 26, 28) at least in sections comprises a friction-reducing slide coating. In this way, a force level required for dispensing and/or setting of a dose can be effectively reduced.
