Abstract
A driving device includes a motor, a wave gear device including a wave generator having first thickness, a flex spline, and a circular spline having thickness larger than the first thickness, a housing functioning as a housing of the motor and including a flange, and an oil seal fixed to the inner side of the flange and extending along the outer circumference of the shaft. The wave generator is set closer to the opposite direction of the flange to configure an internal space with the members. When the internal space is filled with grease, a distance between the oil seal and the wave generator is set smaller than distances among the other members.
