The pedal comprises slots 11 at two lateral sides respectively and a supporting portion 13 in the middle. One end of the pedal is provided with an axial hole 14 communicating with the supporting portion 113. An illumination unit has light-generating portions 21 and a coil seat 22. The portions 21 are disposed in the slots 11 and have circuit boards connected to the coil scat 22 within which a permanent magnet 23 can rotate. An axial rod 31, which is in the axial hole 14, carries a first gear 32 which meshes with a second, small gear 332 fixed to a larger gear 331 which meshes with teeth 231 on the permanent magnet 23. Thereby, the permanent magnet can be rotated rapidly by means of the differential ratio of the gears to produce enough electric power. An end cover 15 has hooks 151 to engage the slots 11. |
