Abstract:
A driving device that can be prevented from being damaged is provided. Abase member includes a frame-shaped part that rotatably supports a movable part via a shaft part provided on an inner circumference side of the frame-shaped part, and an elastic structural part extending to an outer circumference side of the frame-shaped part. The elastic structural part of the base member is joined to the pedestal, and this allows the difference in amount of thermal deformation generated on the base member and the pedestal to be absorbed by deformation of the elastic structural part, thereby preventing the driving device from being damaged.
