Abstract
A lens barrel that is capable of miniaturizing and thinning an image pickup apparatus by enabling to switch manual lens drive and electric lens drive with a simple mechanism. A lens barrel is mounted on an image pickup apparatus that supports an operation member rotatably. A drive barrel engages with a lens holding member to drive it in an optical axis direction. A motor transfers rotation to the drive barrel through a transfer mechanism. A switching mechanism switches between electric lens drive that drives the lens holding member by transferring rotation of the motor to the drive barrel and manual lens drive that drives the lens holding member by transferring rotation of the operation member to the drive barrel via an elastic member that rotates together with the operation member according to a user's operation. The drive barrel engages with the elastic member while shifting to a photographing area.
