PURPOSE:To facilitate the assembly of a hub generator by providing a plural number of slice shaped protruding portions for each outer circumference of plastic rings which are provided so that planet rollers are brought into contact with each sun roller with pressure, and thereby engaging these protruding portions with a plural number of protruding portions provided for the inner circumference of a stationary cylindrical body fixed onto an axle. CONSTITUTION:When a bicycle is running a hub body 4 integrated with a wheel is rotated together with a side cover body 5 and a shaft 25, a first planet roller 24 rotates on its own axis while being revolved in the same direction via the shaft 25. This constitution thereby allows a first sun roller 23a to be acceleratedly rotated together with a planet carrier 23, and also allows a second planet roller 26 supported by the carrier 23 to rotate on its own axis while being revolved. A second sun roller 22a therefore is also acceleratedly rotated, so that electric power is generated by a power generating coil body 20. In this case, a plural number of protruding portions are provided for the inner circumference of a stationary cylindrical body 8 fixed onto an axle 2, a plural number of slice shaped protruding portions provided for the outer circumferential sections of elastic rings which allow the planet rollers 24 and 26 to come in contact with the sun rollers 23a and 22b with pressure, is engaged with the aforesaid protruding portions, so that assembly can easily be processed.
