PROBLEM TO BE SOLVED: To provide a bayonet mount having a simple configuration. SOLUTION: A first member 11 on one side of the bayonet mount 10 being attachable or detachable by rotating includes a first plastic supporting member 20 and a first ring member 30 like a metallic plate. A second member 12 on the other side includes a second plastic supporting member 40 and a second ring member 50 like a metallic plate. The first supporting member has such a shape that is constituted by a simple cylinder including a first cylindrical body-supporting face 21 and a first ring-supporting face 24 rising vertically as a basic form. The second supporting member 40 also has such a shape that is constituted by a simple cylinder including a second cylindrical body-supporting face 41 in contact with the first body-supporting face 21 as a basic form. Consequently, these supporting members 20 and 40 can be simply manufactured by molding by use of a mold, and the ring members 30 and 50 can be simply manufactured by pressing.
