置。[Claims for Utility Model Registration] (1) A circular spline, a flex spline inside the circular spline, and a wave generator that bends the flex spline non-circularly and partially meshes with the circular spline. In the wave gear device, the wave generator includes a non-circular member and a bearing fitted between the member and the flexspline, the bearing being covered by a cover, This cover has two surfaces: a surface that presses the retainer of the bearing, a surface that locks onto the bearing on the opposite side of the bearing and is provided in all or part of the circumferential direction of the bearing. A wave gear device characterized in that the cover has a substantially U-shaped cross section, consisting of three surfaces that are connected and a surface that has a recess or groove on the outer periphery. . (2) The wave gear device according to claim 1, wherein a plurality of slits are provided in the radial direction on the surface of the bearing that presses the retainer. (3) The wave gear device according to claim 1 or 2, wherein a plurality of hemispherical convex portions are provided on the inner surface of the surface of the bearing that presses the retainer.
