Zusammenfassung:	The invention relates to a device for adjusting the blade angle of a rotor blade of a wind power plant, the device including a gear rim (4) supported on the blade (1) as well as a gear wheel (5) with power units, supported on the centre of the rotor, for turning the gear rim and the blade angle of the blade together with it. According to the invention, between the gear rim (4) and the gear wheel (5) there is a power transmission element (6) of a material with a weaker abrasion resistance than the materials of the gear rim and gear wheel, the power transmission element being arranged to prevent a direct contact between the gear rim and the gear wheel.
