The structure unit further includes two pairs of inner diagonal panels provided substantially along diagonals of the rectangular cross section of the unit space, each of the pairs of inner diagonal panels consisting of panels located on the same diagonal and each of the panels having one end portion connected to the inner surface of one of the outer panels and an opposite end portion separated from an opposite end portion of the other panel of the same pair by a predetermined distance in a central portion of the unit space.
