Abstract
An optical device includes: an optical member which is formed of a plate-shaped part and on which light is incident; a frame so provided that the frame surrounds side surfaces of the optical member and made of an elastic material more elastic than the optical member; a shaft that supports the optical member and the frame in a swingable manner and is made of the elastic material; a support that supports the shaft; a first restricting member provided on a plate surface of the optical member; and a second restricting member that is provided in a position separate from the optical member and comes into contact with the first restricting member when the optical member and the frame swing.
