Abstract

PURPOSE:To simplify the shape of bayonet rings, by installing the second fitting member which is relatively turnable in the space between the first fitting member which holds the bayonet ring and the ring, and which is energized in the direction of the optical axis. CONSTITUTION:A bayonet ring 4 is fitted with a screw to the first fitting member 3 fixed to the rear end of a fixed drum member 1 of a lense drum. The second fitting member 7 is installed in the space formed by the first fitting member and the bayonet ring, so that the second fitting member 7 makes relative turn against the first fitting member around the optical axis. A spring member 9 which has energizing force in the direction of the optical axis is fixed in the space 8 between the first and second fitting members. A very narrow clearance is formed by the first and second fitting members and the bayonet, and because of the clearance, the second fitting member can move along the direction of the optical axis when this accessory is fitted to the camera.
