The invention concerns a device for the conversion of rotary into axial movement with planet rollers supported at an equal peripheral distance and driven by a drive shaft, and with a thrust body that is axially-displaceable through the planet rollers which are supported to be rotatable around their fixed axes in an axle-driven carrier and with drive groove via which the planet rollers, driven by their carrier, engage in at least one screw-type groove on the thrust body which is displaceable along the axis of the carrier; the device should be of simple construction and have as low a frictional loss arising from the movement conversion as possible. For this purpose, the carrier is fixed to the drive shaft rotating in its axle. There is no power transmission during movement conversion between the drive shaft and the carrier via the parts that are tooth-engaged in one another.
