At least the lower faces 15 and 6 of the plurality of respective wooden materials 1 and 2 of the front board part 3 and the floor joist board part 4 are stuck with dampproof sheet 16. The sticking range of the dampproof sheet 16 to the wooden material 1 of the front board part 3 is the whole area of the lower face 15 and approximately 1/2 of the height of the longitudinal both sides 17 respectively. No dampproof sheet 16 is stuck to an area of the both sides 18 in the short side direction. The dampproof sheet 16 to the wooden material 2 of the floor joist part 4 is stuck to the longitudinal side 20 and the side face 21 in the transverse direction as well as the whole area of the lower face 6.
