PURPOSE: To freely set the undulation of a green by allowing a mat laid under the green to include a plurality of vacant parts partitioned by partitioning walls and to be connected with a mechanism for charging and discharging the bead-shaped fillers into each vacant part.
CONSTITUTION: When a selector valve 30 of a mechanism 20 connected with a bead bag (vacant part) 18 is turned to the I-side, the pressurized oil is supplied into a hydraulic cylinder piston 24, and pistons 24a and 22a rise, and the inside of a bead bag 26 is filled with filling material, i.e., beads B. Accordingly, the vacant part 18 expands, and the green part in the upper part rises. Further, when the selector valve 30 of the mechanism 20 is turned to the O-side, and the pressurized oil is discharged from the hydraulic cylinder piston 24, the pistons 24a and 22a lower, and the beads B are discharged into the bead piston 22 from the vacant part 18. Then, the vacant part 18 contracts, and a layer 12 in the upper part and the green G part are made recessed.
