The lens barrel includes a first frame, a second frame, a drive actuator, and a transmission mechanism. The second frame includes a substantially cylindrical main body and a gear portion. The gear portion is disposed on the inner peripheral part of the main body. The gear portion transmits the drive force of the drive actuator via the transmission mechanism. The transmission mechanism includes a first transmission gear portion that engages with the gear portion, and a second transmission gear portion that is provided coaxially with the first transmission gear portion. The transmission mechanism includes a clutch. The clutch can temporarily disengage the transmission of the drive force between the first transmission gear portion and the second transmission gear portion. The imaging device includes the above-mentioned lens barrel and an imaging element that converts an optical image formed by the above-mentioned lens barrel into image data. |
