Abstract
A lens barrel for an automatic focusing camera is provided with an annular changeover member arranged so as to be manually rotatable about the optical axis, and further arranged so as to be manually movable in a direction of the optical axis. A first clutch mechanism is provided for releasing a connection between the annular changeover member and an annular focusing member, to permit independent rotation thereof, when the annular changeover member is in an AF mode setting position, and for forming the connection therebetween to thereby form a rotationally dependent structure when it is in an MF mode setting position. A second clutch mechanism is provided for forming a connection between a drive shaft and the annular focusing member when the annular changeover member is in the AF mode setting position, and for releasing the connection therebetween when it is in the MF mode setting position.
