PROBLEM TO BE SOLVED: To provide a travel bag having a power generation function, locking/unlocking a key using the generated power, and having an excellent security function.SOLUTION: Electricity is generated by a power generator 9 by the rotation of a wheel 4, and the generated electricity is stored in a storage battery 10. The stored electricity is used as power for operating a drive mechanism 12 of a key cylinder 7 or controller 11. When an operation portion 8 is operated, a request signal is transmitted outside the controller 11. When the request signal is received at an electronic section 6b of a key 6, a response signal including an ID code is transmitted from the electronic section 6b. The controller 11 having received the response signal, determines whether or not the received signal is the response signal sent from the key 6 corresponding to a bag 1, and only when the received response signal corresponds to the bag, a control signal is transmitted to the drive mechanism 12, the key cylinder 7 is rotationally operated, and the bag 1 is locked/unlocked. |
