PURPOSE:To easily and surely execute the linkage of link mats by coupling a member to be coupled between the coupling member of the flange of one mat and a coupling member on the external surface of the air chamber of the other divided mat and coupling a member to be coupled between a coupling member on the external surface of the air chamber of one divided mat and the flange of the other divided mat. CONSTITUTION:A recessed face fastener 19 and a projecting face fastener 20 are installed at a flange 4 on the upper face of a divided mat 1 and on the external surface of an air chamber 6, and the recessed face fastener 19 and the projecting face fastener 20 are attached to the flange 4 on the lower face of the divided mat 1 and on the external surface of the air chamber 6 as well. The projecting face fastener 19 placed at the flange 4 on the upper face of one adjacent divided mat 1 is coupled with the projecting face fastener 20 placed on the external face of the air chamber 6 on the lower face of the other divided mat 1 and the projecting face fastener 20 placed on the external surface of the air chamber 7 on the upper face of one divided mat 1 is coupled with the projecting face fastener 19 placed at the flange 4 on the lower face of the other divided mat 1 so that the divided mats 1 can be linked. |
