Japanese Patent JP7053112
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide bellows showing a long life, superior washability and superior economical efficiency.SOLUTION: A bellows 5 of this invention comprises a bellows-like cylinder 6. The cylinder 6 has a feature that several bellows elements 7 formed by airtight connecting an upper plate part 7a and a lower plate part 7b of thin-plate or film-like ring by outer edges 8a, 8b are arranged in a vertical direction, an inner edge 9b of the lower plate part 7b of the upper bellows elements 7 and an inner edge 9a of the upper plate part 7a of the lower bellows elements 7 are air-tightly connected and outside valley-folded parts 10 of the connected cylinder 6 are formed in an arcuate shape. In addition, the upper surface 7c of the upper plate part 7a of each of the bellows elements 7 is formed to be inclined gradually downward.SELECTED DRAWING: Figure 2
