Abstract
An image blur correction apparatus includes a correction optical system for correcting an image blur, an actuator for driving the correction optical system, a plurality of resilient members provided on an outer periphery of the correction optical system, the resilient members being provided substantially angularly equally divided into at least three locations about an optical axis of the correction optical system, and a guide member for movably guiding the correction optical system along a direction orthogonal to the optical axis of the correction optical system. The plurality of resilient members and the guide member are disposed within substantially the same plane orthogonal to the optical axis. In a case in which the actuator does not perform the drive of the correction optical system, the plurality of resilient members hold the correction optical system substantially at a center of the optical axis.
