Abstract

A camshaft adjuster (1) for an internal combustion engine is provided, which includes a housing (21) and in which a relative angular position between a driving gear (22′) and an output element allocated to the camshaft is adjustable. In a first connection region (28), the housing is connected in a fixed manner to a support element (20) which is connected in a fixed fashion to a plastic toothed ring (19) in a radially outward direction in a second connection region (29). The outer surface of the carrier element (20) fits an inner surface of the toothed ring (19) in the second connection region (29). The carrier element (20) makes it possible to bridge the radial gap between the toothed ring (19) and the outer surface of the housing (21), and the second connection region accurately predefines a position of the toothed ring (19).
