A dose setting mechanism for a drug delivery device is disclosed. The mechanism comprises an inner housing (5) having an outer housing (17) and an outer groove (30; 31). The inner housing is occluded disposed inside the driver that can lock the flexible tab (21) relative to the inner groove during delivery of a dose within the inner housing so that the driver follows the path of the inner groove. Alternatively, the driver (7, 9) having either one of the lock members (11; 11 ') is guided, the spindle is advanced, and the cartridge stopper is moved. A dial sleeve (3) is disposed between the inner and outer housings and is rotatably engaged with the inner housing. [Selection] Figure 4 |
