A driving switch(75) for driving a pump is mounted n the valve block. The button is fixed to the valve block and operates one of an air supply valve(V1) and an air discharge valve(V2) through seesaw motion. The fixing member fixes the button to the valve block. The connector connects the air supply and discharge valves to the button fixed by the fixing member to make the valves cooperate with the button. The fixing cap fixes the edges of the air supply and discharge valves to the valve block. |
