Abstract
A parallel moving device includes a fixed plate provided on a housing side, a moving frame provided on an optical system side, and three pin-shaped members each of which is provided between the fixed plate and the moving frame and has one end coming into contact the fixed plate and the other end coming into contact the moving frame to support these members, the pin-shaped members allowing the moving frame to move in a direction substantially perpendicular to an optical axis of the optical system. Each of these pin-shaped members supports the moving frame in parallel to the fixed plate, has ends that contact the fixed plate and the moving frame and that have curved surfaces, and tilts in the substantially perpendicular direction in response to movement of the moving frame about the one end as a fulcrum.
