The system further includes a controller controlling the respective switching valves to allow the respective chambers to be expanded or contracted and check valves each arranged between the compressed air supply source and the switching valve and openable from the compressed air supply source toward the direction of the switching valve, by which it is possible to individually adjust pressure in the respective chambers.
