A vane-type camshaft adjusting device for an internal combustion engine, with a drive pinion (2) connected in driving relationship to a crankshaft, and a winged wheel (7) connected rotationally fast to a camshaft. The drive pinion (2) a hollow space (6) which is defined by a circumferential wall (3) and two side walls (4, 5), into which hollow space (6) is inserted the winged wheel (7) having at least two wings (9) on its wheel hub (8). Limiting walls (10) define at least two working chambers (14) in the hollow space (6) of the drive pinion (2), and each of these working chambers (14) is divided into two hydraulic pressure chambers (18, 19) by one of the wings (9) of the winged wheel (7). The limiting walls (10) of the drive pinion (2) are in sealing contact by axial sealing strips (13) with the wheel hub (8) of the winged wheel (7), while the wings (9) of the winged wheel (7) are in sealing contact by axial sealing strips (17) with the circumferential wall (3) of the drive pinion (2). According to the invention, the sealing strips (13) of the limiting walls (10) of the drive pinion (2) and/or the sealing strips (17) of the wings (9) of the winged wheel (7) are connected to one another to form a one-piece or a multi-piece sealing cage (24, 26, 34) by which the hydraulic pressure chambers (18, 19) in the hollow space (6) of the drive pinion (2) are sealed from one another both radially on the circumferential wall (3) of the drive pinion (2) and/or on the wheel hub (8) of the winged wheel (7) as also axially on the side walls (4, 5) of the drive pinion (2).
