Abstract
A bending meshing type gear device includes a wave generator; an external gear that is disposed on an outer periphery of the wave generator, and is bendably deformed as the wave generator rotates; a first internal gear meshing with the external gear; a second internal gear that is disposed on one side in an axial direction of the first internal gear to mesh with the external gear; and a wave generator bearing that is disposed between the external gear and the wave generator in a state where movement in the axial direction of the wave generator bearing is restricted. The external gear includes a protrusion on an inner periphery of the external gear. The protrusion engages with the wave generator bearing to restrict movement in the axial direction of the external gear.
