摘要： It is an object of the present invention to provide an image blur correcting device having a dimension reduced in any one direction perpendicular to the optical axis of the incident light, and a camera equipped with this device. The image blur correcting device 300 includes a pitching movement frame 205, a pitching guide mechanism 304, a yawing guide mechanism 306, a pitching direction electromagnetic actuator 312, and a yawing direction electromagnetic actuator 314. The pitching movement frame 205 supports a third lens group G3 for performing image blur correction. The pitching guide mechanism 304 guides the pitching movement frame 205 in the pitching direction. The yawing guide mechanism 306 guides the pitching movement frame 205 in the yawing direction. The electromagnetic actuator 312 drives the pitching movement frame 205 in the pitching direction. The electromagnetic actuator 314 drives the pitching movement frame 205 in the yawing direction. The electromagnetic actuator 312 and the electromagnetic actuator 314 are provided substantially opposed to each other and with a second optical axis A2 interposed therebetween.
