のを防止することを特徴とする波動歯車。[Scope of Claim for Utility Model Registration] Consisting of a circular spline, an inner flex spline, and a wave generator that rotates the flex spline by bending it in a non-circular shape, the wave generator consists of a non-circular cam plate and a cam plate. Consisting of a ball bearing installed on the outer periphery, when the cam plate is rotated, the shape of the non-circularly bent flexspline is rotated, and the circular spline and flexspline are relatively adjusted at a reduction ratio corresponding to the difference in the number of teeth. It is a wave gear to be rotated, and a retainer for holding each ball is provided between the inner ring and outer ring of the ball bearing of the wave generator, and this retainer can be inserted and removed from one side between the inner ring and the outer ring. In the wave gear, one side is formed as a substantially annular plate, and a partition wall for holding each ball at a constant interval extending from the plate portion between the inner ring and the outer ring is erected, wherein the annular plate A headed projection is provided at the top of the partition on the opposite side of the section, and the headed projection has a second approximately annular plate occupying a space between the inner ring and the outer ring. A wave gear characterized in that the formed hole or recess is configured to be snap-fitted, thereby preventing the retainer from falling out from between the inner ring and the outer ring.
