<p>PURPOSE: To provide satisfactory design and to reduce cost by arbitrarily selecting the number of bases. CONSTITUTION: Two rectangular bases 11 of a common longitudinal dimension and a larger lateral dimension and four rectangular bases 12 of this common longitudinal dimension and a smaller lateral dimension are laterally arranged side by side through a groove 5 for cutting separation, plastic molding is integrally performed, thus a shared bases original object 10 is constituted. In this case, the respective bases 11 and 12 are provided with totally four key grooves 7 for positioning of linkage while dividing them two by two on the upper and lower sides of respective side faces, totally four holes 4A to be hung for linkage while dividing them the left and right sides of planar parts and totally four holes 4B to be hung for linkage while dividing them two by two on the respective upper and lower faces. The key grooves for linkage or the holes to be hung are respectively provided on the bases and even when this object is cut off at any part, it can be linked. Then, edge tools not shown in the figure are finally added to left and right lateral end parts.</p> |
