Abstract
A drive wheel for integration into a clock movement, in particular into the clock movement of wristwatches, with at least a dented section by whose teeth a downstream wheel is rotatably drivable and at least a non-dented section which has a diameter chosen in such a manner that the part-circular circumference of the drive wheel in the non-dented section blocks the downstream wheel against rotation while the teeth of the downstream wheel face this section. The non-dented section of the drive wheel includes at least a flexible element that is arranged, seen in the direction opposite to the direction of rotation of the drive wheel, immediately after the dented section and that includes an elasticity essentially directed in radial direction of the drive wheel for the change of the diameter of the non-dented section of the drive wheel in the range of the flexible element.
