    • PROBLEM TO BE SOLVED: To provide an interior speed change hub for a bicycle capable of suppressing degradation of the lifetime of a bearing caused by large loads even when a sun gear is integrated with a hub shaft. SOLUTION: The interior speed change hub 10 comprises a hub shaft 21 fixed to a frame, a driving body 22, a driven body 23, a planetary gear mechanism 24, a first one-way clutch 25, a second one-way clutch 26, a clutch control mechanism 27, first and second bearings 28 and 29, and third and fourth bearings 30 and 31. The driving body has a cylindrical shape to be connected to an input body, and the driven body is connected to an output body. A power transmission mechanism has a planetary gear mechanism, and transmits the rotation from the driving body to the driven body. The first one-way clutch transmits the rotation in one direction of a carrier to the driven body. The second one-way clutch connects/disconnects the driving body to/from the driven body. The clutch control mechanism connects/disconnects the second one-way clutch. COPYRIGHT: (C)2005,JPO&NCIPI
