Claim:
An adjusting device for adjusting a camshaft relative to a camshaft gear wheel driven by a crankshaft, comprising first and second parts provided for the adjusting the camshaft arranged on the camshaft gear wheel and on the camshaft, and the adjusting device further comprises an input shaft, an eccentric drive element that can be driven by the input shaft, the first part including webs, which are spaced apart in a peripheral direction and between which chambers are formed, the second part including internal gearing, and several teeth, which are arranged in the chambers spaced apart from each other in the peripheral direction, each having an inner contact surface for contact with the eccentric drive element and an outer contact surface for engagement in the internal gearing and which are adjustable in a radial direction when the input shaft rotates, wherein when the input shaft rotates, the first and the second parts can rotate relative to each other in a self-locking way through engagement of the teeth in the webs and in the internal gearing, and when the input shaft rotates, the teeth in the chambers can execute rotational movements about rotational axes parallel to a rotational axis (A) of the first and the second parts.
