The at least one second tooth has a second maximum chain-engaging width defined in the axial direction. The first maximum chain-engaging width is larger than the second maximum chain-engaging width. The at least one second tooth includes a first chamfer provided between the first axial surface of the at least one second tooth and the driving surface of the at least one second tooth.
