Therefore, the outer case 10 and the inner unit 20 can be relatively slid by the first shaft 60 and the second elongated hole 12. As a result, the inner unit 20 is slid relative to the outer case 10 using a configuration in which the first shaft 60 that supports the outer case 10 and the inner unit 20 is passed through the second long hole 12 that is a guide. A structure to be moved can be formed, and it is not necessary to provide these separately. As a result, the number of parts can be reduced.
