Abstract

The invention relates to a device (1) for the electrical adjustment of the relative rotary-angle position between a camshaft (2) and a crankshaft of an internal combustion engine, with an adjusting gear (3) which has a driving part (4) fixed with respect to the crankshaft, a driven part (5) fixed with respect to the camshaft and an adjusting shaft (8) connected fixedly in terms of rotation to an adjustment-unit shaft (6) of an electrical adjustment unit (7). In order to achieve a simpler type of construction which, moreover, is distinguished by quiet running, there is provision, according to the invention, for the adjusting shaft (8) to be arranged in a radially floating manner.
