1. A lens barrel configured to transition between an imaging state where imaging is enabled and a retracted state where imaging is restricted, the lens barrel comprising:
a moving unit configured to move a first optical member included in an optical system between an imaging position located on an optical axis of the optical system and a shifted position shifted from the optical axis;
a base member configured to movably support the moving unit;
a cylindrical member disposed on an outer circumference of the base member; and
an operating member configured, when operated, to cause relative movement between the cylindrical member and the base member,
wherein the cylindrical member includes a sliding surface on which the moving unit slides and an engagement portion engageable with the moving unit,
wherein the moving unit slides on the sliding surface and moves the first optical member from the imaging position to the retracted position in a case where the lens barrel transitions from the imaging state to the retracted state, and
wherein in a case where the lens barrel is in the retracted state, the moving unit is engaged with the engagement portion and restricted from moving.
