Abstract
An oscillating gear device includes an axially fixed gear piece rotatable around a first axis and an axially oscillating gear piece that oscillates while being inclined with respect to the first axis. A plurality of pins held by one of the gear pieces engage with a plurality of tooth grooves of the other gear piece in engagement regions at a predetermined length in longitudinal directions of the pins. A formula r/r=Z/Zis satisfied, where ris a distance between an arbitrary point on the central axis of the pin in a corresponding section corresponding to the engagement regions of the pin as viewed in the radial direction of the pin and the first axis, ris a distance between the arbitrary point and the second axis, Zis the number of pins of the one gear piece, and Zis the number of tooth grooves of the other gear piece.
