PURPOSE:To prevent the shaking of a floor board by juxtaposing a plurality of semi-cylindrical bodies successively different in heights which have lateral side walls different in heights and inclined upper surfaces to keep a narrow space between the adjacent side walls. CONSTITUTION:A semi-cylindrical body 13 successively different in height which has lateral side walls 14 different in height and an U-shaped section opened downward is formed, and the upper surface 15 of the semi-cylindrical body 13 is inclined obliquely. A plurality of the semi-cylindrical bodies 13 are juxtaposed to form an inclined surface having the flat upper surface 15 as the whole and keep a narrow space 16 between the adjacent side walls 14, and the lower parts of the side walls 14 are integrated together by a connecting part 17. Thus, the resulting slope floor board is bendable to some degree by the space 16, and it can exhibit the regulating function in middle direction to an unevenness when laid on a slab. |
