To prevent the deviation of the rotating position of a lens unit without causing an increase in the size of a camera main body and a deterioration in operability.
A main-body-side mount 20 in a blind hole state where a nearly regular octagonal aperture 20a is formed is provided on the front of the camera main body. Meanwhile, a lens-side mount 22 formed in nearly regular octagonal pillar shape is provided in a protruding manner on the back of the lens unit. A holding and fixing part 30 comprising a pair of lock members 31 and 32 and a moving mechanism 33 moving the lock members 31 and 32 slidably is provided inside the camera main body. The lock members 31 and 32 respectively have trapezoidal notches 31a and 32a formed to be fit to the lens-side mount 22. The holding and fixing part 30 holds and fixes the lens-side mount 22 inserted in the main-body-side mount 20 so as to bring the inclined surfaces of the respective notches 31a and 32a into contact with the side surface of the lens-side mount 22 inclined at about 45° to a holding direction.
