A shake correction mechanism 1 has an elastic support member 2 for elastically and oscillatingly supporting a lens barrel 10 at one point, and first and second actuators 3a and 3b for applying oscillating forces to the lens barrel 10. When a moment is applied to the lens barrel 10 by the first and second actuators 3a and 3b, the elastic support member 2 is subjected to elastic deformation. Thereby, the lens barrel 10 is oscillated to tilt the optical axis thereof in a desires direction. Thus, the lens barrel 10 is oscillatingly driven without use of a rotary joint or the like as employed in the conventional gimbal mechanism. This arrangement enables to miniaturize the shake correction mechanism.
