Abstract
A rotary drive apparatus that rotates a flywheel holding a mirror and a lens includes a motor and the flywheel. The flywheel is supported by the motor and is rotatable about a central axis extending in a vertical direction. The flywheel includes an accommodating portion including lens, an insertion opening located at an upper portion of the accommodating portion to allow the lens to be inserted therethrough, a support surface located below a light path of reflected light in the accommodating portion to support the lens, and a slanting surface radially inside of the lens in the accommodating portion and opposite to a radially inner surface of the lens, located above and below the light path of the reflected light, and slanting radially outward with decreasing height.
