A camera can reduce thickness of a driving member in the diameter direction is disclosed. The camera comprises an actuator, a driven unit and a driving member that rotates around the image-taking optical axis by the driving force from the actuator and transmits the driving force to the driven unit. Herein, two gears are formed integrally on the outer and inner circumferences of the driving member, and of these two gears, a first gear is interconnected to the actuator and a second gear is interconnected to the driven unit, and the two gears are formed at different positions in the direction of the image-taking optical axis in the driving member.
