PROBLEM TO BE SOLVED: To provide bellows capable of avoiding early wear in a scope of a terminal pleat or a terminal part and having long service life even when a joint is greatly bent. SOLUTION: These bellows are integrally formed by a uniform material and are made of a rubber elastic material. They include at least one pleat part extending in the longitudinal direction of the bellows, and this pleat part has a terminal pleat formed as a substantially half pleat only partially on one side on at least an end face. In the bellows in which the terminal pleat is connected with a terminal part for fixing the bellows on a face on the opposite side to the pleat part in the axial direction, the terminal pleat 3 has one pleat trough part 6 and two pleat top parts 7 and includes at least one load release pleat 5 formed into bellows shape extending in the longitudinal direction. The load release pleat is arranged in a scope in which the terminal pleat 3 is extended in the axial direction and/or on a side face of an end face of the terminal pleat 3 corresponding to a connection part 4.
