Abstract
A power generation mechanism includes a first movable member, a second movable member, a twisted coil spring, a power generator, and a housing. The first and second movable members are gears. First and second wound parts of the spring are wound around a first center shaft in opposite directions. Initial elastic energies ie1 and ie2 are respectively applied to the first and second wound parts, absolute values of ie2 and ie1 being equal. The second movable member is turnable by a force from outside the mechanism, engaging teeth of the first and second movable members together to turn the first movable member. With ie12 accumulating on the first wound part and with the teeth disengaged from each other, the first center shaft is turned in an opposite direction by ie12 to generate power in the power generator. Also, the first center shaft is turned by ie1 and ie2.
