PROBLEM TO BE SOLVED: To easily attach and detach even a bayonet ring which is too thin to operate with its side face in a hand with respect to apparatus provided with bayonet rings attached and detached by so-called bayonet mechanisms and a camera being typical one of these apparatus. SOLUTION: The camera body side is provided with a circular arcuate groove 101 and a fixing claw 102 projecting over the groove. A bayonet ring 30 is provided with a protrusion 32 fitted into the groove 101 and a locking claw 33 which is put under the fixing claw 102 and is locked by the fixing claw when fitting the protrusion 32 into the groove 101 and turning it. A part farthest from a mark 31 of the bayonet ring 30 is raised by pushing a part of a mark 31 of the bayonet ring in such a state that the bayonet ring 30 has been turned up to a detachment position.
