PURPOSE:To prevent the generation of vibration noise by installing a springy means installed between the contiguous blocks so that the contiguous blocks are springily supported. CONSTITUTION:A metal leaf spring member 61a is installed as springy means, and the length is set a little shorter than the length in the lateral direction of the link inserting vacant space 14 of a block B. Said springy means is inserted into the gap 14A between the upper wall 14a in the link inserting vacant space 14 for the block B and the upper edge of a link L. Since one continuously patched surface 13A1 and the other continuously patched surface 13B1 are nipped by the flat insertion part 62 having the equal width to the thickness of the link inserting vacant space 14 and the both edges 62a and 62b of the insertion part 62, all the vibration of the block can be absorbed. |
