Abstract A bellows device having an automatic diaphragm-interlocking mechanism comprises a camera mount, a bellows portion, a lens mount and a guide rail. The camera mount is provided with an interlocking lever operatively associated with the shutter mechanism of a camera body so as to be operable in response to a diaphragm blade stop-down signal during shutter release. The lens mount is provided with a diaphragm-interlocking lever operable to actuate a diaphragm lever operatively associated with the aperture mechanisms of the lens. The bellows device includes a rocking member comprising a pair of arms extending along the guide rail, the arms being moveable in opposite directions. The rocking member is operable by the interlocking lever. The device also includes an actuating member having detecting portions corresponding to and engageable with the arms of the rocking member. The actuating member is operable to actuate the diaphragm-interlocking lever upon detection of the stop-down signal through identical one of the pair of arms irrespective of whether the actuating member is installed in the normal or the reverse direction with respect to the camera body.
