ABSTRACT:
In a diaphragm driving device of a lens barrel which is provided between a diaphragm driving ring and a cam member and which rotates the diaphragm driving ring correspondingly to a positional variation amount provided by the cam surface of the cam member during the stop-down operation by a diaphragm interlocking device provided on a camera body, there are provided a pivotable member and a limiting member. The pivotable member has a first arm coupled to the diaphragm driving ring and a second arm engageable with the diaphragm interlocking device of the camera body, and is pivotable with respect to an axis substantially orthogonal to an optical axis lying between the first and the second arm. The limiting member is provided between the cam surface and the second arm to limit the range of pivotal movement of the pivotable member.
