A wind power station has at least one rotor. The rotor has at least one rotor blade, preferably two or more rotor blades. The rotor blade is operatively connected to a rotor shaft. The rotor blade can rotate about a substantially radially extending adjustment axis. At least one adjustment device is provided in order to adjust the rotor blade. Installation effort and labor effort as well as the costs are reduced by the adjustment device having at least one cam disk interacting with a control disk, and by the cam disk being disposed such that the rotation axis of the cam disk coincides with the adjustment axis of the rotor blade.
