Abstract
Disclosed is a gearing device for a seat including a first internally toothed gear, a second internally toothed gear, an externally toothed gear, and an eccentric member. The first internally toothed gear includes a rotation center axis. The second internally toothed gear has the rotation center axis in common with the first internally toothed gear and is rotatably supported by the first internally toothed gear. The externally toothed gear is arranged to an inner side of the first and the second internally toothed gear, to thereby mesh with the first and the second internally toothed gears. The eccentric member rotates the externally toothed gear such that a rotation center thereof follows a path around the rotation center axis, rotatably supports the externally toothed gear about the rotation center, and rotates about the rotation center axis in response to a rotational force being externally input thereto.
