In a flexspline of a wave gear device, an annular flange thereof is constructed from a first annular part bent at a right angle from an outer peripheral edge of a diaphragm, and a second annular part caused to inwardly protrude at a uniform width from a leading end of the first annular part. It is possible for the annular flange to be disposed within the region where the diaphragm is formed, as viewed in the direction of an axis of the device. An outer diameter can be reduced to a greater extent than with a "silk hat"-shaped flexspline; and when a hollow wave gear device is manufactured, a hollow diameter can be more readily increased than in a case where a cup-shaped flexspline is used. |
