This paper presents the development of the bending bellows named "barrel type bellows" for the multi-functional vacuum tube. Conventional bellows with a bending axis outside of the bellows is imposed the complex motions of bending and sliding, and the stress concentrates on the pleat near the end portions. Based on the numerical analysis, it is found that the concentrated stress is reduced by making the outer diameter increase continuously from the both ends toward the center. As a result, the offset width of the bellows decreases and the vacuum tube becomes small. The endurance test shows that the operating cycles are over 30, 000, which roughly corresponds to that predicted from the calculated stress and the fatigue data of the thin stainless sheet in Refs. 2) and 4).
