Is prevented. Further, the movable frame 81 is prevented from interfering with the shutter unit 70 even when the camera C is tilted from the normal photographing position after the upper housing 40U is mounted.

In the lens barrel 2, the prism P and the first lens group L1 are mounted on the main body 41 of the upper casing 40U in a separate process from the lower casing 40L, and the second group holding frame 10 is connected to the rear opening 41a.

(4) Since the lower housing 40L includes the limiting portion 46a in the lid portion 46, the movable frame 81 can be prevented from falling off from the lower housing 40L. Since the restricting portion 46a is provided on the lid portion 46, before the lid portion 46 is attached to the main body portion 45, the process of placing the movable frame 81 on the shake correction support portion 48 of the lower housing 40L is obstructed. do not become.
