In the wave gear device including a wave generator, the bearing has an outer ring having a flat outer circumferential surface that engages with the inner circumferential surface of the flexspline, and at least one of both sides of the outer ring in the axial direction has a circumferential surface. A wave gear device characterized in that a recessed portion extending in the direction is formed. (2) A wave gearing device comprising a wave generator that includes a circular spline, a flex spline, and a flexible bearing, and bends the flex spline non-circularly through the bearing and partially meshes with the circular spline. In the bearing, the outer ring has a flat outer circumferential surface that engages with the inner circumferential surface of the flexspline, and at least one of both sides of the outer ring in the axial direction extends from the inner ring toward the outer circumferential surface of the outer ring. A wave gear device is characterized in that it is formed so that its width in the axial direction increases.
