The controller controls opening/closing of the electromagnetic switching valves in an order of first control, second control, and third control. In the first control, the control valve is opened. In the second control, the first supply/discharge switching valve and the second supply/discharge switching valve are opened in an opened state of the control valve. In the third control, the control valve, the first supply/discharge switching valve, and the second supply/discharge switching valve are closed.
