PROBLEM TO BE SOLVED: To provide a key chain where keys and the like are attached and detached easily, and to maintain a stable coupled state by an easy operation. SOLUTION: The key chain is provided with a wire-shaped holder body 1 with torsional elasticity and a coupling body 2 connecting the holder body 1 in a loop shape by being coupled to both end parts of the holder body 1. An inserted latching part 3 projecting sideways from the end part is fixed to an end or both ends of the holder body 1. A coupling cylindrical body 4 with a latching opening 5 having a cross section to fit the outside of the inserted latching part 3 is provided on the coupling body 2. A rotating space 7 where the inserted latching part 3 inserted inside the coupling cylindrical body 4 with torsional force applied rotates into a direction to restore the original shape by the elasticity of the holder body 1 is provided so that the rotating inserted latching part 3 is latched at the deep inside of the latching opening 5.
