PROBLEM TO BE SOLVED: To provide a bellows seal which connects separate containers and reduces vibration quantity transferred through the seal. SOLUTION: This double bellows seal is constituted by a plurality of rings containing a first and a second end ring 312, 314 and an intermediate ring 316, and a first and a second bellows 308, 310. The first bellows 308 is formed of a flexible material which is connected air-tight between the first end ring 312 and the intermediate ring 316, and has a torque with respect to the axis of these rings in a first rotary direction. The second bellows 310 is formed of a flexible material which is connected air-tight between the second end ring 314 and the intermediate ring 316, and has a torque with respect to the axis of these rings in a second rotary direction which is opposite to the first rotary direction.
