The invention relates to a driving and dosing device for an injection device for administering a liquid product, in particular a medication. A product dose to be administered can be set by means of the driving and dosing device. The driving and dosing device comprises: a) a housing (4), b) a dose indicating element (10), around the circumference of which a dose scale (10b) is arranged, c) a pointing device (4d) and a dosing element (3) that can be gripped in particular by the user of the driving and dosing device, the dose indicating element (10) being rotatable, in particular screwable, relative to the pointing device (4d) and about an axis of rotation (L) and a value of the dose scale (10b) that corresponds to the set dose being readable by means of the pointing device (4d), in order to set the dose to be administered by rotating the dosing element (3) relative to the pointing device (4d), d) a bearing element (9), with which the dose indicating element (10) is in an engagement that causes the rotational or screwing motion of the dose indicating element (10) relative to the pointing device (4d), characterized in that e) the bearing element (9) can be moved together with the dose indicating element (10) relative to the housing (4) and along the axis of rotation (L). |
