In a strain wave gearing (1), a thrust force (F1) applied on an externally toothed gear (4) during an increased-speed operation causes the externally toothed gear (4) to move along an axis in a first direction (a1), and the output-side end surface (4c) thereof is pressed, by a prescribed force, against a friction surface (11a) of a friction plate (11) integrated with a rotating shaft part (5a) of a strain wave generator (5). Torque transmission efficiency can be reduced only during increased-speed operation, by means of a friction loss occurring between the externally toothed gear (4) and the friction plate (11). When large load torque is applied from an output shaft (8) which is an output-side member during reduced-speed operation, retention torque of the strain wave generator (5) which is an input-side member during speed-reduction operation can be reduced.
