Abstract
A planetary gear mechanism of the invention includes a housing, an input shaft that has an eccentric portion whose center lies on an eccentric axis that is displaced from an axis of input and output shafts, and is supported by the housing to be rotatable about the axis of the input and output shafts relative to the housing, an oscillating face plate that eccentrically oscillates via the eccentric portion, such that its rotation relative to the housing is restricted, and an output shaft to which an internally toothed gear that internally contacts and meshes with an externally toothed gear formed on the oscillating face plate is mounted, and which is rotatable about the axis of the input and output shafts relative to the housing. As the input shaft rotates, a circumferential position at which the externally toothed gear and the internally toothed gear mesh with each other changes, and rotation of the input shaft is delivered at a reduced speed to the output shaft. First pins that protrude from the oscillating face plate engage with insert holes formed in the housing, so that rotation of the oscillating face plate is restricted.
