[0020] Furthermore, the number of the plates is two, which are divided into a first plate 11 and a second plate 12. The second plate 12 is located below the first plate 11. The lower surface of the bottom plate 1 of the first plate 11 is in contact with and coincides with the lower surface of the bottom plate 1 of the second plate 12.
