`ABSTRACT
`(57)
`A drive mechanism suitable for use in drug delivery devices
`is disclosed. The drive mechanism may be used with injec-
`such as those permitting
`tor-type drug delivery devices,
`a
`the delivery dose. The drive mechanism may
`user
`to set
`a dose dial sleeve, and a drive sleeve. A
`include a housing,
`clutch is configured to permit rotation of the drive sleeve and
`to the housing when the
`the dose dial sleeve with respect
`dose dial sleeve and drive sleeve are coupled through
`the
`clutch. Conversely, when the dose dial
`sleeve and drive
`rotation of the dose dial
`sleeve are in a de-coupled
`state,
`to the housing is permitted and rotation
`sleeve with respect
`of the drive sleeve with respect
`to the housing is prevented.
`In the de-coupled state, axial movement of the drive sleeve

`delivery of the required dose of medicament. Dose setting
