Abstract
A first driving device includes a motor including a rotating shaft, a speed reducer, and a supporting member. The speed reducer includes a rigid gear, a flexible gear configured to partially mesh with the rigid gear, and a wave motion generator coupled to the rotating shaft and configured to come into contact with the inner circumferential surface of the flexible gear, bend the flexible gear, and move a meshing position of the rigid gear and the flexible gear in the circumferential direction. The wave motion generator includes a projecting section projecting along the rotating shaft. The rotating shaft is supported by the supporting member via a bearing including an inner ring and an outer ring. The outer ring of the bearing is supported by the supporting member. The rotating shaft and the projecting section are coupled to the inner ring of the bearing by tight fitting.
