Abstract

PURPOSE: To considerably reduce working steps and obtain the bayonet device which has high accuracy and sufficient fitting strength by constituting the bayonet member of the lens-barrel coupling to the bayonet on the camera side with plural members.
CONSTITUTION: Lock rings 6A, 6B constituting the bayonet member may be readily made by pressing and even with the lens-barrel construction in which a mount member 8 is constituted turnably to a lens-barrel 2, it is possible to make the mount member unremovable from the lens-barrel and turnable. Even a spring member 16 may be made much simpler and at lower cost in production than it is formed with a single part through machining. The spring member 16 enables the deviation of the optical axes of the camera and lens-barrel to be prevented, and enables the engagement of the lens-barrel and the signal member of the camera to be made in their correct engaging position, thus making it possible to perform receiving and transmitting of the correct signal in exposure control operation.
