A lens barrel includes a first lens set configured to move manually along an optical axis, a second lens set configured to move electrically along the optical axis, a first holding member configured to hold the first lens set, a second holding member configured to hold the second lens set, a driving member configured to move the second holding member along the optical axis, a transmitting member configured to transmit a driving force of the driving member to the second holding member, and an urging member configured to relatively urge the transmitting member and the second holding member along the optical axis. The first lens set is movable within a range of motion of the second lens set. The urging member is displaced when the second holding member interferes with the first holding member.
