Disclosed is a pocket-type sprocket comprising two groups of pockets (3) for chain members (10) of a chain section which pass the sprocket at an angle a relative to the sprocket axis (8), said groups of pockets (3) being disposed next to and offset from each other. In order for the angle a to be determined exclusively by the diameter d of the material used and the internal width bi of the chain members (10) at a given number of teeth of the sprocket, it is ensured that the contact between the chain members (10) and the pockets (3) is limited to the area of the faces of the teeth.
