Claim Text:
1. A strain wave gearing having an annular rigid internally toothed gear, a flexible externally toothed gear that is disposed coaxially on an inside of the rigid internally toothed gear and is capable of flexing in a radial direction thereof, and a wave generator that is disposed coaxially on an inside of the flexible externally toothed gear; the flexible externally toothed gear being flexed in the radial direction by the wave generator and partially meshing with the rigid internally toothed gear; and, when a position at which the rigid internally toothed gear and the flexible externally toothed gear mesh moves in a circumferential direction thereof as the wave generator rotates, the gears rotating relative to each other in correspondence to a difference in number of teeth between the gears, wherein the strain wave gearing is: the flexible externally toothed gear is provided with a vibration-powered generator; and the vibration-powered generator generates electric power by flexing motion of the flexible externally toothed gear that is repeatedly flexed as the wave generator rotates.
