    • 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 F1 is applied to the wave generator in the direction toward the open side of the flexible external gear, and during speed increase, thrust force F2 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 F2 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.
