In a wave gear device provided with a cup-shaped flexible external gear, the difference in the direction of the thrust force applied to the wave generator during speed reduction or speed increase is used to reduce the input-side holding torque. During speed reduction, thrust force F 1 is applied to the wave generator in the direction toward the open side of the flexible external gear, and during speed increase, thrust force F 2 is applied in the opposite direction The plug of the wave generator is pressed against the friction plate mounted on the motor housing by the thrust force F 2 applied during speed increase, and the friction force that is produced is used as part of the input-side holding torque for restraining the wave generator from rotating.
