PROBLEM TO BE SOLVED: To provide an image blur correction unit in which assemblability is improved without performing a plurality of steps of positioning adjustment at one time at the time of assembly by allowing ultrasonic motors to be individually detached, and in which the ultrasonic motors can be accessed without disassembling the image blur correction unit at the time of maintenance.SOLUTION: An image blur correction unit of a lens device which includes a plurality of ultrasonic motors each having a drive slider provided with an output shaft projecting in the vertical direction with respect to the drive direction, comprises a lens movement frame to which an image blur correction lens is fixed and which is provided with a plurality of long holes which has the longitudinal direction in the plane vertical to the optical axis and into which the output shafts are slidably inserted; and a stationary part which is fixed to the lens device, supports the lens movement frame in a movable manner in the plane vertical to the optical axis and which is provided with an attachment part to which the ultrasonic motors are fixed in a detachable manner from the side not facing the lens movement frame and which has an open hole penetrating in the optical axis direction.SELECTED DRAWING: Figure 8 |
