PROBLEM TO BE SOLVED: To ensure excellent leakproof properties by installing plural pieces of modules combined into one, making up each module from a material making a rubberlike elastic body the basis, and installing at least two waveform areas to be united by means of vulcanization. SOLUTION: Gangway bellows are one to form a corridored connecting part between two vehicles, and it is provided with plural waveform areas or waveform 2 formed by means of vulcanization without sewing and adhesives. A rigidity imparting part 3 on a peripheral rigidity imparting part 3 forms a peripheral frame with a nearly rectangular outline 35 equipped with a nearly rectilinear part connected by a corner area, in and around and axis XX'. A frame 2, a flat area 20 and the peripheral rigidity imparting part 3 and 30 are all made up of a vulcanized elastic body, for example, rubber, and further they are formed out of vulcanized rubberized cloth, if desirable, and the waves are united with each other by vulcanization which imparts those of mechanical coupling and waterproofness to the frame 2 and the peripheral rigidity imparting part 3. |
