Brake disc for a vehicle disc brake, comprising a radially inner hub portion (1a), intended to be non-rotatably joined to a wheel hub, and a surrounding, radially outer disc portion with opposing friction surfaces. The outer disc portion is formed by two disc elements (4) joined to the hub portion, and which are separated by spacers (7a–7f), which define passages for cooling air and of which at least some (7a, 7b) are in the form of fan vanes to generate an airflow from the passage inlets (10) at the outer periphery of the disc to the passage outlets (11) at the outer periphery of the disc.
