A bicycle rear hub (10) is configured to improve the external appearance and the resistant to corrosion of a drive body (19). The rear hub (10) also has a hub shaft (15), a hub shell (16), a pair of bearing units (17) and (18), a one-way clutch (20), a sprocket (21), and a cover member (23). The hub shell (16) is rotatably mounted to the hub shaft (15) by the bearing units (17) and (18). The drive body (19) is mounted to one end of the hub shell (16) by the one-way clutch (20) that transmits rotation from the drive body (19) to the hub shell (16) in one direction. The sprocket (21) is fixedly mounted to a radially outward-facing surface of the drive body (19). The cover member (23) is mounted to the drive body (19) to cover the radially outward-facing surface of the drive body (19) and with its tip edge contacting the outside lateral surface of the sprocket (21). <IMAGE> |
