Abstract

Provided is strain wave gearing (1), in which on a fastening surface between a boss (33) on an externally toothed gear (3) and a first end plate (8), formed are tapered fastening surfaces (331, 81), inclined with respect to an orthogonal plane that is orthogonal to a central axis (1a). Additionally, on a fastening surface between an internally toothed gear (2) and a second end plate (10), tapered fastening surfaces (21, 101) are formed. Due to engagement of the tapered fastening surfaces (331, 81) and engagement of the tapered fastening surfaces (21, 101), a firm fastening state can be formed, and radial-direction displacement of the first and second end plates (8, 10) that arises due to radial-direction load can be reduced. Decentering between a wave generator (4) and support bearings (7, 9) originating in the radial-direction displacement can be prevented or controlled, and the acting of unnecessary radial force on the wave generator (4) can be averted.
