<p>PROBLEM TO BE SOLVED: To provide a leveler capable of easily corresponding to stepped sections in two kinds or more of height. SOLUTION: The leveler A is formed in a triangle pole shape with a base 1, an inclined plane 2 at an acute angle to the base and a substantially vertical perpendicular 3 to the base while a large number of substantially parallel slits 4 to the above-mentioned perpendicular 3 are formed into the leveler A while leaving certain wall thickness sections 5, 6 to the base 1 and the inclined plane 2, and the wall thickness sections 5, 6 are formed of an easily cutting material.</p> |
